KH opening sequence gag

I couldn't help it! I was always wondering what happened to Riku after that huge wave crashed on him... XD I know, I'm supposed to be studying/ CGing the monster poster T_T but I HAD to do this, too good to pass up. ^^

Does anyone know how to CG skin really fast? I think that I'm gonna need that soon. *rips out hair, staring at the unfinished ffac poster*
