The background catches my interest in particular. I absolutely love how you used different brushes/textures for each different part/colour. To think of how many layers you must have had simply astounds me. Nice, crisp vectoring, so points for that too.

As for the light source, I find it particularly difficult to spot, I know it's coming somewhere from the left due to the shadows, but I for one don't think it's pronounced enough, not that it matters, since the entire wallpaper seems evenly lit to me x3 (though I did notice that you made the right side SLIGHTLY darker than the left, or maybe it's just because I'm sleepy. In any case, that's a good thing, because since the shadows are fanning out to the right, it's only natural that the majority of light is coming from a source on the left.)

Overall, an 8/10. =3

Keep up the good work Cat~
