The season one He-Man episode "Dree Elle's Return" has quite a few moments of stupendous animation. This is largely in part thanks to artist Byron Vaughans whose storyboards for this episode are amazingly expressive and for want of a better word "cartoony". In this one panel featuring Clawful you can see that Byron was clearly more suited to illustrating traditional cartoons, rather than the action-based cartoons of the eighties! I hope to feature more of Byron's boards, because they are simply beautiful!
