AWW its such a shame! its a great vector but...well it looks like you rasterized the background white images. I mean that is what created the jaggy edges on the crosses and etc. in white. If you used something that actually Vectored the image and kept it a vector (without rasterizing it) that would have been way slicker! You need to get Adobe Illustrator for walls like this, its ment for clean slick cut lines. Would really improve your vectors hehe.

Ah, evil raito. =] i would have this on my desktop if it weren't for his expression, because don't like his sneering face much, lol *off topic* anyway, his collar (his left side, our right) looks kinda funny. and i would try another design rather than the swirls (something more unique/meaningful/tasteful? can't seem to find the right word) to add the the bg. but what you have is awesome! great job.
