I love the beautiful colours, the sharp detail and the pose. The background is smooth and nicely OOF, the only improvement for me would be to remove the dark background directly above the birds head and to the left of the image. A very pleasing image Dan.
The flock would definitely appear to be tame! IQ is obviously top notch. I love the yellow ring around the eye and the green sheen in the head feathers. I'd be tempted to clone the vertical thing on the beak. The dark spot doesn't bother me too much, perhaps lighten it a bit.
The background looks alot better viewed large than what it appears on the thumbnail. That is a particularly pleasing shade of blue you got there. Excellent deatils, good comp. I'd be tempted to darken the sheen on the bill (not get rid of it fully, just tamed a little). A lot of us would be in heaven to have such a tame flock of this species!
Sweet portrait Dan, beautiful detail and color, love the subtle green catching the light atop the head and the finely detailed mane behind. Backdrop color compliment it perfectly. I like the sheen on the feathers, but I feel it is a bit bright on that one band across the chest and top of bill...should be an easy fix in PS
