hmm i would either make the tongue just a bit smaller or else move it forward. As it is right now, it doesn't look like there's much room for the throat O.o
Also, I see what you're trying to do with the beak thing where the mouth ends, but to me it looks wierd. Mayeb if you made the muzzle/beak i different color, maybe paler, it would look better, more like the bird beak i think you want.
As for the colors, not too shabby, would make the pinkish flesh patches a bit more palid though. As for the neon green you have for the tongue, go ahead and keep that, but i would suggest making it a bit darker.
I'm guessing you're still planning on shading? :3
Hope I'm not discouraging you here!!
