Also: more cat like features. Four paws (Opinicus!) instead of talon-hands. Face more like a cat with a beak than a bird head on a cat body. And crests are good!
I'm probably a greyshades disaster, as much as I like bright colours, I shy away from them. Possible earthtones?
Beaks - I tend to prefer short and slightly curved, so probably small predator birds.
Big predator beaks (like eagles) are right out - too aggressive looking for me. Also kinda open to reasonably proportional pointed beaks (like, maybe woodpecker shaped?)
