Fatter, but losing weight

I may make a mold of this guy when he's done. Maybe I'll finish him as a complete conversion figure.

Usually sculpting the cheeks and nose adds a lot of weight due to the thickness of the Magic-Sculpt. So I'm trying out a new idea.

I bought some foam balls at the craft store. I cut them in half and hollowed out the backs to contour to the cheeks and nose. Then I glued them to the face. I'll trim them up a bit when they're secure. Then I'll cover them with Magic-Sculpt. I hope to achieve fuller cheeks and a larger nose without adding so much weight.

Hey, it may be a conversion figure, but I want it to be a COOL conversion figure.
