doesn't look good...
those sigs or whatever they are shouldn't be on a wallpaper, makes it look bad + adds a lot of contrast, the bg effect is not too bad, u can get away with it, he pic of trunks on the left just looks bad, not the q, but it's not blended or cutted out, it's not "part of the wall" just like the sigs. For wallpapers, make sure it doesn't have too many contrast, and that the wallpaper is "one whole thing"
so yea, IMHO, not good, even for ur first, but keep trying
