Very nice BG, I feel it would make a GREAT abstract sig but with this one the colors work but it just doesn't feel right. The focal is way off to the side and the flow just isn't really there like it could be because of it. It doesn't feel empty, just like it's not complete. I would have tried some c4d work to blend in the focal or some multi layered blending or even some clipping or smudge work as well, though that might not fit this background all that well.

Nice job though! Fon't is decent as well as the colors and your lighting sure has come a long way! Great to see! You got some great CNC's from other memebers so follow their advice and I can see you being a top notch sigger in no time!
