Beautiful portrait, great details and sharpness.

[Paul Keeble]

Not much wrong with that is there!
Looks great.

The only thing I can find is a little posterisation in the background - nit-picking is all.

[Marina Scarr]

Lovely bird, well exposed with a nice pose. I can see evidence of your selection around the bird esp around the head and beak.

[Mike Delgado]

Nice one.

[thijs broekkamp]

Nice one, good composition. But I think it could use some more sharpness.

[Joe Senzatimore]

Great low angle makes this a winner.

[Diane Miller]

The odd look in the BG is JPEG compression. Now I see it in the original -- didn't notice it before. Try using a higher quality setting.

Marina, I have not done any PP here except cropping and overall sharpening and overall NR. As Diane has later pointed out it might be due to jpeg compression.

[arash_hazeghi]

I like the low angle, pose and details. there are compression artifacts in the BG

Rest is already mentioned above.
