This is late but- They have distinct cat ears, I've never seen a bird with those type of ears before (but then again I'VE never seen it before, if you have then this wouldn't be accurate). They don't have bird legs, there would normally be the "thighs" and then a bird leg. This drawing displays a more cat or mammal paws rather than talons, and although some style preferences can make it seem like that (and your style is fine!), maybe you could've implemented a more bird-like leg style. The body anatomy also could/maybe resemble that of a cat's, although it's less prominent because of the pose and I wouldn't count it as a big factor. It's pretty much fine and fits well with your style.
