The bird does in fact pop from the BG well. Well exposed, and there are some interesting lines in the perch. I wish the bill didn't merge with the rear wing quite so much, it gets lost a bit there.
You could probably safely crop a bit from the left (perhaps 10% of the free space there)
I also like how the Heron and the perch pop out from the BG. I like the wing detail and the steel blue color of the Heron and the small red eye. The perch is fine with me.
