he thinks about cut off snickers
this looks like a pretty good start for a wallpaper. To hide this missing part try to create a good dark shadow of a player. To make it more dynamic, try to experiment with your work and bring new elements into your walls, something like c4d renders or good grunge textures as a new layer... if you use CS4 or more you can play with colors, you have channel mixer, color balance, hue and saturation in a different layers, if you use any of these settings in a different layer try to change a layer mode of it and play with opacity.
hope I helped you somehow
