Turnarounds of a playable reptilian race for an MMO, showing customizable color variations (round 2 of this design: [link]
). The bottom three are females. I based the color schemes on chameleons for the males, iguanas for the females. Emulating real reptile biology in having larger, more robust females than males is one of the ideas I'm most proud of in the development of this race, because I can't think of another MMO that does this. Mostly, I've seen males with biceps larger than their female equivalents' waists.
