i like a lot of your stuff faith, but i really think this one is sloppy >.< the green and blue accents dont make alot of sense and the bg is very chaotic. im not trying to sound mean but i just dont know where im supposes to be looking. mebe if the big rock on the right/middle wasnt there and the green splash was blu-ish ^.^?
Colors and quality are really off and again the c4d blending could be better, mood is nice but the green kinda kills it : S
The rock is low quality, it seems like it's detracting from the rest of the sig. I really like the left part though. Maybe if you made the right half similar to it?
