Here's my progress on sculpting Phastor's character tonight =) I had a bit of a false start about an hour in, when I noticed some problem spots in the geometry that forced me to correct that in the base model and start over, but I still ended up getting quite a bit done!
When I continue on him next, I'll refine the details I started sculpting tonight, and paint his proper colors on him. A lot of the muscle definition will be obscured by his fur, so it'll be a much more subtle effect overall than what you see here.
Enjoy!
