mangozac: Yeah, I wanted skinny but lots of striated musculature. His power is not in his muscles (which aren't really muscles as he's made of living metal), but in his powers.
geomod: Thanks dude! He's gone a little differently to how I had imagined, but I'm happy so far
Anvils Hammer: Cheers! The anatomy is fairly accurate so far with some mistakes (eg. the division between deltoid & trapezius) that I don't feel I need to correct. I didn't intend to go too mad with accuracy, as he's not even flesh & blood, let alone human! Still, for sculpts like this to look good, one must always bear real musculature in mind. I did take this snapshot before I had finished the current pass. See the back, forearms and lower legs for evidence of this! I have an anatomy poster right next to my desk
A couple of books on the shelves.
Definitely casting & selling.
