Good detail, DOF, BG and angle in frame. I agree with Chris, wish I could see the fish a bit better.
You might try a version with a modest uplifting of the center of the curve. It brightens things enough that the fish pops better from the BG, whites on head still good.
Dan - nice sharpness, dof and placement in frame. I agree with the comments and suggestions above. It's great that you can get these views of the osprey.
Love the eye contact and the techs. Very well executed. Agree with Chris about view of the fish.
So cool to have these opportunities, and you're making the most of them!
