Ok, this is awesome. I'm redesigning my Aven Fanwalker based on this.
The plane is based on the American dust bowl. Leonin are pumas and lynx, Aven are Corvids. Which means he's a blue jay, not a cardinal. Real life jays don't have dimorphism, but this is fantasy, so these Aven can be dimorphic: the males are jays and the females are crows or magpies.
