Lose the border. I understand that learning new techniques is fun, but you cant overdue it. I feel as though in this one, you may have done that a little bit. Take away some of the c4d renders you have in there, add a nice bg, and get rid of the splatters, they dont fit in there. Also, change up the colors, looks a little monotone to me.
Well, that depends on the outcome. If it looks bad, than its bad and if it looks good, its good. IMO, its not a matter of a completely scratched sig or a partially scratched sig that makes it look good. On topic, I love that one. The splatter brushing is a nice addition and very nice text thar. Gj mate.
