It's my first i've made without help, i'd like suggestions and opinions thanks ^^

here

Hhhmmm...not bad...I like that concept of yours...well..the only thing that I did not like there is the emptyness of the wall on the right side and it realyy needs some lil cleaning..it's a little bit blurry to me...I suggest adding soem texture and text there would be great...well...good luck on that wall...I hope that will be accepted...

Nice effort considering this is your first time on your own.
some advice...as you see around the symbol and the tear marks the lines are toojagged (thats the impression im getting from viewing the wallpaper)
very plain and there is alot of empty space (for some wallapers the empty space works but not for all)
mayne add some text or at least add some sort of texture or brushing to the background to give it more depth
hope that helps
later

Thanks I'll try.

And what do you think about this

You should listen to pana I guess... :). He knows better. I think you shouldn't have that edge, maybe if you could do something as if it was burned or such. you could turn this into a really grungy wall. Also, you could work on that black bg, add some textures, or maybe, you could do something to look like a door or something. Um... just my thoughts on that >.>.

The second wall is also nice, but needs something extra. But, I suggest you to start a new topic for the new wall.

Keep it up.

Thank you for the councils I see what I can do ^^

For the first wall I find it really nice at the first look. The concept is great and character's well done!

But like the others, I don't like the background... To simple. You could make it looks like a curtain or a piece of fabric... Or more like a wood wal... Or... Could be nice to see this character trough a tear in a asian door... (Paper and wood).

If you change the background, the wall will have a new look... You should give a try and come back with a new texture for it.

Note : I think your wall's not on the rigth size..

Second wall :
The stars are pretty strange in the situation... The spiral's fine but it does not give enough movements to Mugen... You probably can add some movement lines to make it more dynamic.
