This was the C-3PO head from the Don Post Scans. I cleaned up the model. Hollowed, Smoothed, added lips and necknolt lips, sharpened detail lines and scaled it to fit my head (23 Inch forehead). The back of the head will be posted here shortly.

Still a work in progress You may have to do some post cleanup along the edges of the lip and the area where the neck bolts attach when you align the front of the mask to the back. Nothing a little epoxy sculpt couldnt fix.
