Very interesting framing. Head angle is good and your subject is well lit. The whites on the edge of the lower wing seem hot on my moniter. Otherwise, this is a good photo. I love the texture given by the black feathers on his back. Good job.
Interesting angle, one I haven't seen very often, detail is super, eyes and exposure pretty good. The ongoing problem with Snowies in flight is trying to get a good balance between the whole bird in the frame with enough detail and little crop. The face detail here is very good, but I'm not sure about the missing wing tips. The shot sure tempts me to get the 400 5.6, love the detail.
This one is not good, it is extreme! Love it, so powerfull and full of action, lovely light and great detail! Exposure looks good in my monitor. Congfratualitons!
