Male vs Female Models

On the left, the male (Prometheus), and on the right, the female (Sonora). I duplicated Prometheus and scaled him down to make Sonora, then to further distinguish her from him, I made her slimmer and shortened her tail feathers. She'll be yellow and a light brownish color, while he'll be a two-tone blue. I'm thinking of having their primaries be the secondary color as well as two feathers in their tail, and then making the body and other feathers be the primary color. The beaks will (hopefully) be orangey (orangy?) and I'll keep both eyes black. I'll have to make eyelids... Bah. I'll work on that next.
