Love the full stretch wing and the side view look of this bird. The background is very nice also. I might reduce sharpening around the body and the head a bit.
Now THAT'S what I've been waiting to see, Gus! Outstanding! Perfect in every way on the bird's pose. The sharpening on the head looks great but it feels a tiny bit oversharpened on the belly - might just be the irridescence of his feathers, though. Could also use a little NR on the BG and then PRINT IT BIG! :D
Gus, I'm copying this to Avian...it's too good for them to miss!
