its good but there's little variation in colour resulting in the depth not really being there, especially in the bit behind the text. Also a well placed C4D which flows and blends well could look good. At the moment id say 7/10, its a nice clan sig.
A couple tiny things and it'd look awesome. Maybe a splatter brush in the empty blue space above the S, U, and the P. Also make the pentool go BEHIND the text not infront.
