I am a potter but telling you how to sculpt it would be like trying to explain drawing it. Do you have a finished pot of hulk's head and you want to add a body? Matching the glazes colors will be difficult at best because even the same glaze can change depending on how it is fired. Also the clay will shrink about 12% if you want to have the head fit into the shoulders some how. So I would suggest making a different full body pot. (A teapot of Hulk doing " I am a little teapot?") You could go to a paint your own pottery for supplies and help. Have fun.
