These guys are shot commonly. Notwithstanding, I still enjoy viewing the shots. But here, I wanted a different perspective. Straight out of the camera at these settings:
I like the idea, but I find the vertical posts distracting, esp. the closest one. I might crop a smidge off the bottom and right, so reposition the bird a bit, and then clone out the middle post.
Yes, the posts should go but I wish the heron was on a better "perch". I would also crop about half of the water at bottom. Otherwise nice silhouette, nicely seen and I like the interesting effect of those highlights in the water.
