That's really cool. All of your customs are really neat. I can't wait to see this one finished.
I'm more of a dio builder than a figure customizer, but I will be attempting to build a fat character to go with the current dio I am building. I'm thinking of starting with a Malikili then plumping him up a bit to give him a grotesque shape. Any tips on applying the "sculpy", drying, painting, etc?
