The only critique i could think of is the positioning of the tongue (though admittingly i don't know how exactly it works with birds - but i'd assume its the same) tongues generally originate at the low back of the throat and here it looks more like the tongue originates from the middle of the lower jaw. It may just be the perspective that i'm looking at it with but i can't help my eyes being drawn to that part in particular as an oddity.

hmm, good to know bird tongues are weird, also i didn't know ducks or whatever the first one was had teeth like barbs. weird to see the eagle has two barb like teeth on its tongue as well
