I've been working on the shapes for the characters and then adding some basic detail to get the feel for there clothes and some basic character.
For the villain of the show, I have tried to channel the likes of 'Skelator' from He-Man and 'Cobra Commander' from G.I Joe. By this I mean a more maniacal villain as opposed the dark, evil villain of a more grown up shown, hence the evil laughter pose. I have also given him armour for an imposing look and made it more pointy and triangular. This especially comes across in the hands. It is in contrast with the hero who has circular hands and gloves, while the villain has pointed gauntlets. I have also used a helmet to mask his true face, again in the vain of 'Cobra Commander'. All you can see is red eyes and the rest is black. It creates a mystery as to what exactly the man underneath looks like. I also used a long, flowing cape as opposed the the shoulder cape for the hero to create more contrast.
