most new people to gfx's problem inst that noone is helping them out with advice its that there always telling them to go to youtube. its good for a few tutorials but you should really go to a gfx site or a tutorial site............back to business, the render looks kinda stretched(remember to hold shift when resizing to keep it even) use some c4d's and effects in the foreground and the background to add flow and depth to the sig. also you should use gradient to make everything blend a little bit more......... thats about all i have to say so id give it a 7/10 for making a pretty descent attempt
