I do like him. I might pull up the middle of the curve just a bit to help the bird pop out a bit more from the background. I looked at it with a dark BG surround, it it really popped nicely, but with my usual light grey BG, the bird seemed a bit too flat.
There are a couple of faint gray smudges in the RU background that I might stamp out.
Nice bird and nice low angle shot. Agree with Randy's suggestions about making the bird pop a bit. Fill flash might have helped in this light situation. Well done.
He looks good...nice study in juvenile plumage. I like the head turned a bit our way. Great low angle too. I agree in raising the midtones, or the overall exposure a tad in post and lighten the reflection in the eye to give it more life.
