One thing we realized in the tests was that even if we got naked models with body paint, the bald caps would never look realistic. After much debate, I decided carefully to alter the design of the character so that it would be more practical. Here's what i came up with. It's a sort of a lotus bud like formation from the top. We could do this with a bald cap, a swim capo and a funnel-tube and some plasticine or some kind of polymer based molding/modeling material.
