Your work is incredible. I once tried to create the real animatronic dragon. Spent a lot of time developing mechanism but later realised that it is too much for on man. If I had your talent, maybe it would go further. I sometimes think about continuing this project and sculpting the skin in zbrush because making sking texture in real clay will took months to me :) Here is the stage where I ended.
