General Chang is based on the Klingon from Star Trek Six played by the wonderful Christopher Plummer, and he is so full of great shakespeare lines throughout that movie that I couldn’t help but put him in creature form.
Cobra Commander on the other hand is just classic. This is his more traditional military suit. maybe one day I’ll paint the crazy eyes Cobra Commander.
Both can be seen in larger form at Etsy

UPdate: Both sold. Thanks for looking.
