Heres my attempt.
Things to add:
Some kind of feathering maybe
Elongate the talons.
Tail feathers or spikes. Looks more like a tadpole tail, but i'm fine with that.
Ideas:
Feather/smudge the white maybe?
Things i don't know how to do:
Paw pads. I mean, just look at those ugly things. They will most likely get scrapped.
