Despite your skill? Dude, your sculpting is impeccable. Some truly beautiful work there, I'm pretty sure if you ever did an Overlord it would smash mine. I was about to ask you where you got the head until I saw that it was mostly sculpted, because its perfect! Seems to me you are of professional quality, myself and I'm sure the rest of the orgers would love to see more of your work on MOTUC.
May I ask what you are using to sculpt with? By the looks of the color I would guess Supey Sculpey Firm. Not trying to divulge any trade secrets or anything, just curious.
