Yeah so this isn't an anime wallpaper, but I did this one for my brother who is CSS crazed (CSS aka Counter-Strike Source)...
He is really happy with the result, but I think it's still missing something....

I used a render as background, though I altered the original colours completely... I added a vector I had on my pc as a special touch and went over it with a couple of different colours, brushes, etc. etc.

I extracted the character from a wallpaper he gave me..

and this is my result... Please comment and critique!
