The render doesnt fit, background is cluttered and those... c4ds? Dont work with the background stock.
Another for the background being totally off from the rest of the sig. The right side is sort of boring as well.
Sorry, but I think its your worst =[ I love just about all of your other tags, but this one just doesn't do it. c4d is way too blurry, and the clouds just dont fit, looks LQ aswell (Sorry) just not one of your better pieces
