I played around with some crops and feel that if you take some off the bottom and left positions the bird less in the center. Something to take a look at.
Jim I like the light, the perch, BG and DOF. The bird`s sitting a little high in the frame for my preference of composition. That being said i`ts nice to see a junco on a perch instead of on the ground.
I like the inclusion of the snowy perch and feel the crop is fine along with seeing so much of the perch. Excellent detail and I like the slight head turn.
