What a wonderful image. I love it! Great moment to press the shutter. The whites look really nice to me and I like the composition. Maybe I would remove those single specks between the bird and the lower edge of the frame? I feel the image would be better without them as I find them a bit distracting. You could even consider removing the white bits in the background as well to make it a very clean image that really puts the bird as the only point of attention. Just a suggestion of course.
Great timing, like the front wing back more to allow better view of head and neck.
the light was obviously pretty bright based on the shadow, yet didn't blow the whites, good job.
Great timing Noelle, as mentioned allready good exposure in the whites. Love the action captured and the snow "spray" under the tail just tops the action captured.
Nice timing. Obviously you saw him coming in as this could easily have been missed.
IMHO the exposure of the feathers is perfect. The snow could be lightened a tad with a bit of post processing but I don't think it's really that far off.
Nice work.
