Wonderfull Yoko!! freat job with the bg!

Nice work!
I like the background, totally fits the style of animation used for this series. Yoko is vectored very well, the colors are nice and soft.

This is cool. I like the mixture of colors and styles.

Hey AWESOME job!
S2 yoko
the theme's awesome liked it a lot!

The sky nice to look. Love Yoko very much

One of the best Yoko wallpapers I've seen to date, totally fits the style of the show.

It is a very good wallpaper, even better that it features Yoko. Beautiful vector work on Yoko.

I would just clean up some of the obvious brush marks on the ground that stand out. Idk if that was intentional or not, but it doesn't make it look too good. Other than that tho' its very nice. I like it.

Your Yoko vector is AWESOME!
I thought it was a scan! Her look is very, very soft and supple almost like you did it with watercolors; I just love it!
I give you lots of respect for originality, but there are still lots of flaws, some big some small, I think you could fix with a bit of work; I don't know how much you (dis)like returning to old walls, but I really think you could make this one like new again.

Starting from Yoko, the only thing I could ever really ask for is more detail on the gun, like make it's edges sharper and it's body more detailed. Right now, it looks sort of like a plastic toy and Yoko is a huntress that uses a real man's gun; it' s important to capture that aspect of her character!
Also, i think the wall's better off without the lens flare reflection circles you used on the right, on top of Yoko. I think it takes away from the beauty of your Yoko vector.

I'm sorry, but I'm not feeling the sky at all. It looks like a crudely pieced collage of sky patches. I also question the sun's placement and it's look. I think it'd be better to just start this one all over.

I like the stylized lines you used for the ground but you have to make the piece as a whole work more together than letting it compete for attention separately.
Someone mentioned the ground and I didn't notice it until I really looked and it seems that the problem is lack of depth. I was going to mention the perspective at which Yoko is being viewed (from above) as not making sense until I saw closely the ledge she was sitting on.
There are some ways you could go about adding more depth:
-More color contrast. Either heavier colors/shades/tints (just enough) on the ledge or brighter colors/shades/tints on the ground...or both. Adding contrast in one of these ways would separate foreground and midground more.
- More detail contrast. I'm not saying you have to add a flower bed behind Yoko but adding little rocks, pebbles, and other things you can imagine from the show would certainly add another level to your composition.

Anyway, I really hope you'll take my criticism contstructively because your Yoko vector made me type all of that. Yes, it is that great and when you have a subject worthy of remaking the sky itself for, you know you've got something to run with!
