I love the pose and open mouth here Akos. I agree on some more NR on the BG. I think it needs a little CCW rotation but I'm not sure. The bird is sharp with great feather detail and a nice light. Well done.
Nice pose, love the view of the tongue! Neat how we can see the foot underwater. NR on BG wouldn't hurt, and there is a dark halo (sharpening?) along edge of top of head, chest, and left edges of legs.
I agree 100% with the above comments, I would also suggest birghtening the eye just a bit, a little lower point of view would've improved this one but I don't know if that was possible, any way I like the light and the open bill a lot Akos! Congratulations!
