The character of Serpentor was a mistake. All the writers needed to do was up the professional psychopath side of Cobra Commander and they would be able to make CC almost an entirely new character. Leave out the mystical mishmash and concentrate on COBRA as a top-tier terrorist threat.
This is AWESOME!!! He looks so bad-A, and I love how you drew him in his Resolute uniform. The shading is really crisp, and the Cobra logo in the background, with the splatter, is a great touch! Good work!
