I don't think the logo in the top left nor the image in the bottom right is needed. Makes it look too cluttered.

The logo really ruins the overall effectivness of this wall.

This wall could probably become a really nice one, but at the moment, it's simply too crowded. First, get rid of the BLEACH logo in the top left. Not only is it crowding the wall, but it was cut a bit edgy. Second, the manga scan in the bottom right.This is also edgy. I can see the attempt put into the spirals around Ichigo and his sword, but quite frankly, it looks crappy. The red dots/spray paint effect aren't helping much either. Third, your credit. Make it SMALLER and LESS VISIBLE. Many people prefer completely textless wallpapers already, but when you want to give yourself credit, make it smaller and in a less noticeable color compared to the background color(s) it's on. Fourth, the fire-y effect around the main part of the image. It's another great attempt, but it's making the wall look worse. Finally, the actual vector used as the highlight of the wall. It's too pixely, and not very well done at all. The best way to go with this wall would probably be simple and clean - a better vector of what you're using with the same sort of cut out (kind of looks like a sword slashed throw it to me) on a black background and nothing more.
