This is a really nice shot especially at 1/250 handheld on a 400mm lens.
I would likely have chosen 1/500 minimum. This is a case where I would have used shutter priority and dialed in a fast shutter speed.
It's not tack sharp but it's quite good. I like the composition and the blurry bkgd. The actual eye could use a slight contrast boost imo. I just love the intensity of eagle stares. Hope that helps - Marko
