Zap's head is an ROC Desert Ambush Duke head on which I sculpted and the mustache and sanded the cheeks. The torso was repainted a solid greed and the lower legs had sculpting and mods to work with the upper legs, then painted to match the upper legs. Matching the color was a bit difficult, but worked out nicely. I love the way those lower legs look with the the modern upper legs. I've used that combination on several customs.
