Sorry, but I'm not sure you're telling the truth. It looks like you just made the head C/P, then you made a black/white version to show that you made one un-colored before you colored it. That, and the bottom of the head is warped and stretched. You can't draw that.
Please prove me wrong, because I'm interested in this head if it's not C/p.
/offtopic theres a warp feature in photoshop that allows you to bend and stretch images, idk if berc uses photoshop but it's a feature.
