I like it, the colors are beautibul for me, althought the second character looks so "dead", because of the dark, i mean the black color is to heavy for the rest of colors I have to say that in graphic design is necesary to kwow when we can use that color.
But your job is great!

I remember this scene lol and i love the cherry blossoms they rock! and its such a cool wall! great work!

Its in my FAVs hehehe

The cherry blossom tree looks lovely.. nice concept.. ^_^

This came out pretty good, bright colors for a cheerful mood, only thing though is that the subjects (Fate, Arf, her maid) look too blurry, like the detail was lost on them. Everything else looks nice and sharp aside from them. Also there's no sense of motion in Arf's tail swinging, so it looks like she simply has two tails. Aside from that I thought this wallpaper came out very well; nicely thought out.

Environmental!! haha! ^^

I agree with the other that the shading is strange
the other two girls' shading are too dark, not like they're under the tree
you should add some ray/light there, just imagine how it's shading is if you are sitting down under a tree
the grass under the tree too, you should add some shade there
i think the grass' color is too bright,,but i guess it's okay cause it makes the wall colorful
and the empty space near the right bottom petals are strange i think

but gotta tell you, the sakura tree is so lovely!
nice idea here, i really think you did well on the bg.

The background is good, but I dont like the shadow, zou cant see anzthing trough it.

The wallpaper is very clean! Nice work on this. The effects in the background are bright enough to be noticable, but not so bright so as to overwhelm her. In short, it's well balanced, and the colors compliment one another.
