Stuart, Good shot. These guys look easy to take as they go to the top of a bush and give out like mad but when you try to take the shot they are gone in a flash. Great capture. I think the light was a bit harsh but you did well. A little bit of selective brightening at the back of the head area would be nice. Killer BG, great pose and great perch.
The repost looks great. I love the details and the pose. I might consider a small crop from the bottom, as the relative position of the bird in the frame is a bit high for me.
