Yeah, it looks like CG. That's probably because... it is CG.
The individual manips are just okay... they were supposed to be in the background of another piece, so I didn't put much detail into them. D'oh! When I chose to do a close up, I decided on the concept as a way to buttress the weakness (relative to my usual standard) of the actual manips. I think it worked, cause this got quite good review. (I think Trouble said it's his favourite of my work.)
