Nice idea i can almost see what you are planning
I welcome the competition not that i have this in the bag but i also like the adrenaline.
I guess i must since i am always behind cause i changed my 1st idea around.
I only bring it up because i also went sci-fi, might want to add that into the title header or a mod might. (Sci-Fi)
Any who looking forward to your results, um since you are using zbrush i can help by saying Mask any areas use, extrude in the tools panel and then go to deformations i think and use the polish features boom that might help you 50% the rest you got to figure out. (youtube vids)
You sound like you got this covered an i am interested.
I am the guy that chats on everyone's entries even 2D. Hope i can help and if i don't you can tell me i am wrong. (i like to learn so if i am, i am happy to learn why.)
Best of luck.
