Skeletor and his golden Havok staff are looking cool.
I like Teelas outfit all though itīs a little bit busy(Goddess, Man-At-Arms, original Teela, 200X Teela and some She-Ra vibes combined all in one...) but her face isnīt my kind of taste.
General Randor is my favorite, i always liked that helmet and you chose a nice color panel for him.
He-Man looks to much current DC/marvel Ironman-ish for my taste. Like in the comics he looks more like Adam with all those armor and in those colors he looks like Adam as a palace guard trainee.
But thatīs just my opinion. Letīs see what else you come up, looks promising so far
