You've got a pretty interesting wallpaper. I like how you've taken the image of the character and doubled it using just white lines in the background - and that's saying something because I usually hate it when people double the same image in a wall! I like the octagon shapes in the background - there's nice spacing between them, but the text on the right is a little hard to read because of the shape behind it being so dark. I'd suggest either lightening the background's octagon or making the text a lighter color. And this is just something I like to do: Whenever I have a character without any ground that's just floating over the background, I put a light shadow under them - that way there's some form of "ground" for them to stand on. I do like the simplicity of the gradient background, and it's interesting how you've broken it up into thirds. That's a neat idea. You've got a very good wall! Keep up the nice work!
