This is the displacement map I used to make the 3-D versions of the flying monkey kick. Couple notes I picked up in this experience: the dark on the sole of the foot is too dark, so it looks too arched in the 3-D, the edge of the foot is also overly dark, creating too much depth. Fingers on back hand should be darker. Tail overall darker, and more "rounded" (i.e. thinner dark edge). etc...
