uggh please stop referring to an artists previous work, if you have nothing else to say .. don't .. i'm sure it's in the rules of posting here or something...
..anyway back on subject this signiture is nice.. background kind of repetative but the colours are very delinquant and shadow eachother perfectly ... i like how you contrasted the render, but maybe towards the top corners of your background make it less like all those squares (i believe i've viewed a tut for that)
