Today I worked on detailing the exoskeleton. I modified his eyes to make them more crab-like, the overall shapes are sharper and pointy and his mouth's got new teeth.
Then I separated all his different facial shell pieces so they feel more like independently moving parts, so he could, in theory, be capable of minimal facial expressions while keeping that crustacean style.
Tomorrow I'll begin putting more shell details like little studs and spikes here and there. Can't wait to texture that dude!
