Well it´s been a while since my last attempt thanks the fact I´m embody laziness with tiny self-trust. Anyway here is a next try. I added some textures in the BG and bloodstains which I like a lot. Every suggestion will be helpful.
PS: It´s still my first attempt to make a wall so be gentle on me =)

Thant's a cool wall you got there! i dont quite like the string of words outlining the buildings...ok that's just my opinion. the way you positioned "scared of pain?" is interesting. i think the guy has jagged lines here & there. btw, which manga/anime does the guy come from? he doesnt look very anime-ish or manga-ish...oh maybe that's because i dont read mangas & have limited knowledge on animes. overall i think it's very cool & it's an excellent start as your first wall! are you sure it's your first?

hmm...i dont want to comment on the blood...im sorry but at first i thought it was paint, in the style of vandals splashing it on. opps. but i must say that the border is quite nice. well if you really want to make it more like blood, then maybe darken the tone slightly. no you should wait for an expert. im not much of any use in this area. good luck! ( sorry if i sounded too harsh...i suck at being gentle xp )

edit:
ah wait i just realised it's from black lagoon! ok my mistake. um actually havent heard of it before...x[

The Bg is nice,but the blood looks not realistic enough,does it fly in the air or stick to the clothes?
Hope this helpful.

Let me just say I think this is a great start! The blood should be a tone or two darker as blood isn't really, that bright. The words floating around the builds a really nice touch in my opinion and I like how you have everything placed in this wall.

Okay here I am to comment on your wall! :D

So first I like this version better than the ancient I saw.

The character still looks great so that's a good start. The font is perfect for the army look and the place is nice. I would make the background behind "pain" in a entire black part but it's up to you... Just a thought...

About the buildings on the background it's really nice. The font of the floating quotes is pretty boring but it can work with the style... But I rather like a more army looking font...

Cause of the darkness of your wall you should probably add some more contrast to the character and turn down a bit the light of it...

About the skyline in the middle... I don't feel comfortable with it now you got a nice building background... But I guess it's working... Maybe make it more horizontal... Just to check.

Like others say, you need to make the blood a bit more realistic! Make it darker at first then try to add some texture to get differences in the color and tone of the red... You'll see how it's FUN to work on blood! LOL :D And you also need to decide if the blood is on the character or on a sort of window or surface between the watcher and the character... So you can decide if you make the blood transparent or not, where you put it and so on...

I like the blood line on top and on the left but why don't you use it as a sort of frame? Could look pretty neat... But it's just an idea ;)

In my concept this enough good wallpaper, but I believe that deberias to correct that is to clean the image of the gentleman, the letters is necessary to work a little, seem a little stiff in the edges of the buildings.

OK thank for the suggestion folks.
First the blood: I´ll try to make it darker, It´s transparent because it´s in the eyes of his victim(or something like this), I like the shape of it now so if it isn´t a big problem I´ll let the shape like it is. Heh yeah zazou you must know it =) trying to revenge about the blood huh?(just kiding)
About the letters over the buildings: Yeah zazou I wanted to make them with the same fonts as the main title but this type of fonts look very blurry when it´s smaller the 15.

About the skyline in the middle... I don't feel comfortable with it now you got a nice building background... But I guess it's working... Maybe make it more horizontal... Just to check.

I quite don´t understand what you mean zazou. Would you explain me this lil bit?

OK thanks for suggestions anyway. Really appreciate that. Soon there will be another version

Ok, first of all, please use only a link or a thumbnail
on the thread =)
don't put the whole wall...

as for the wall, the red is way to saturated... tone it down a bit
the scan is fine, don't do anything to it.
the buildings in the background look too real to match the scan,
it looks like you just filterd it. o.O
th red biuldings are too plain, use some texture or some kind of
pattern to make it more interesting to the eye. get a grunge brush
and use it as an eraser on them and see how that works.
start with that ^.~
I'll come back to see how it goes
good luck~!

I'm speaking about the red skyline in the middle (don't tell me you don't see it! :D) it's a city shape.. but you already have a nice background behind it... So it's kind of looking strange to have two style of city in only one wall... See what I mean?

So I was wondering what would it looks like if in stead of having the skyline tilted... Why not make it horizontal and less saturated?

Is that clearer?

Post a new version as soon as possible...

I see now. Hmm when if I´ll make it horizontal it will cause the loss of that effect which I want and will change the position of the "scared of pain" title which I like very much now, mainly that inverted "pain". Is it a big problem to you? I´ll try to make a new version tonight but I´m too tired from my collage so maybe there will be no energy left but at least I´ll try =)
---EDITED---
OK with this version I just want to know if the saturation is good. Sould be the blood much more darker or it´s dark enough?

All around the blood is looking a bit better.. It's still a bit simple cause you don't have a lot of contrast in your blood but I guess it's fine this way...

But now the skyline is way too bright and saturated... It doesn't match the rest of the scan...

I like the tipt style with the text that's for sure but you really need to do something with this skyline now cause it's looking pretty strange now with the dark buildings behind him...

But I don't really know what to say about it...

The splatter of blood seems a bit blurry but it can be my screen...

Keep up the good work! :)

Well I tried to find something up and this is all I found out...Somehow I have the lack of inspiration...
Is this better? Or if you have some concrete idea I would really appreciate that.

I think those bullet make the wall even more random cause it's really photo stock and not manga looking bullets then you didn't change the saturation of the cityline scape...

I would love to help you but I guess adding some stock wont help... You need to add some TEXTURES to the red part of the wall...

Well I´m back and all the time I was thinking what to put into the red skyline to not look so strange...hmmm and this is all I thought up. I put there this circles which I like quite a lot but I don´ t know if others will. Hope it works:

Well the skyline looks fine... But it's drawing much more attention than the scan.. So I guess it's a bit too much of brightnes...
Try to turn it down a bit and make it less obvious.

You also need to continue the texture in the font for PAIN cause right now it's looking pretty strange this way...

Good luck! ;)
