Kidneys! (I want it to become some sort of greeting)
Anyways, great job. He looks amazing. Just a tip though. I've noticed your sculptures have a bit of a rough texture. If this is on purpose ignore everything I'm about to say. I took a break from sculpting a while back and my clay dried out naturally and it was almost impossible to get it "working" again. I searched around and found out they sell this clay softener for sculpey and if you pass a brush lightly over the surface it also smooths the clay out. Thought you might find it helpful. Alcohol supposedly works too.
