Totally awesome. I loved He-Man as well, this is definitely the best He-Man piece I have ever seen. The Frazetta influence with your take on Skeletor is pretty much a near perfect take. Great Job as I'm sure you are well aware.
I'm just glad someone else out there likes Skeletor.. He's my childhood hero. Awesome pics of him, in his original costume etc too.. It's really hard to make him look cool and sinister wearing the no shirt / underwear look, but you've captured it beautifully..
