Absolutely STUNNING!!!! That looks fantastic dude. Great sculpt and interesting casting methods. Awsome how it all fits together like that. Whats a roto casting mean? Is it like the gamesworkshop kinda casting, with a spinning centrafugal machine?
I love the weight you have sculpted in the creaures skin on the legs. Has a sort of realistic tortoisy-ness to them. Awsome detail in all of it mind, but the legs stand out as highlight.
Were all the moulds for this done in 2 part silicon rubber? Or did you paint the rubber onto them making a jacket mould?
Cant wait to see your tutorial.
