I like the pose with the raised foot and the ruffled head/neck feathers though a slight head turn towards you would have been even better. Good exposure, colors, and sharpness. The vertical comp works well here, but I would suggest a crop from the right and more room on the left if you have it.
Good exposure and sharpness. The composition does not work IMO. I would like to see more room in front of the bird and not so much wasted space in the back.
I have to agree with Maxis´ suggestion about taking some room out from the right, other than that, the walking pose, nice light, vivid colors, great detail, clean BG, ambient and textures are superb! Congratulations!
