i dunno man, imo its a bit lacking, i'd bring out your colors more, the text looks pretty good for the abstract style, the focus is just not real clear (looks like the green/blue line is the main part right now). If you up the contrast (make ur blacks more black) and bring out the c4d's a bit more i think it'd end up with a more even composition. Try it, if you dont like it then leave it as is, just suggestions ^_^ conclusion: it has potential but as it is i think you can improve it
I agree with Daecu. It is lacking in contrast (something I always struggle with myself...) and depth, but those can be similar in some respects. I think it's a very good basis for something more to come from but I don't think this should be a finished work. I'm basically repeating everything Daecu said... but he's right.
