for the "muscle fibers" on the chest, are you planning on adding a bit more of a radius on the rounds? it looks great as is, but a bit more radius on the rounds would make the "fibers" look a bit more like muscles rather than just a piece placed over muscle, if that makes sense. helmet looks like it came out great too by the way!
Very nice work! What type of clay are you using? Also, are you planning on making a mold?
I second the clay question!
the gray one is a brazilian brand of clay "Dim clay - firm" and the brown is a comercial brand medium clay "massa de modelar profissional acrilex" (professional modeling clay acrilex) ^^
