Oh man! I really love this comp! Absolutely wonderful setting, and like Axel said, the snow really adds to this one. I might be tempted to try adding a bit of light to the owl's face/eyes just to punch it up a bit, but I definitely love it as-is anyway! Great capture.
Absolutely superb image, I may be tempted to brighten the eyes just a little, not too much because I don't think they would be very bright in that light.
The wind in the grass,the snow ,the bird pose make this image outstanding.I think that litle selective levels on the owl ,especially in the eyes is needed.Congratualtions!
