This is from a blind set up these little guys were all over the place, managed to get a few good images of them. Images adjustments in Lightroom medium sized crop.

I like the colours in th eimage and also the composition. The bird is quite small in the frame but I think this works, good exposure on the plumage showing good detail.
Great pose and I like the snow on the perch. BG is a bit distracting and could be better but it's not bad. I think I would like to see just a bit more DoF to keep things sharp right out through the tail.
