No wonder you were so happy this morning Sid . Beautiful capture with excellent timing, lighting and I love that you were to make eye contact with both GBH. Placed well in the frame with excellent detail and such intimate interaction. Love it. No nits for me.
Sid,
All of the image capture technicals look fine. The interaction and behavior between the Great blue Herons is outstanding.
IMO more room at the bottom would make this a stronger images. You have enough room at the top to just lower lens a bit.
Overall a very nice image.
Overall very nice, and the interaction could not be better. I agree a bit more room bellow, and there a couple of odd dark blotches between the tail and right side of frame that need to be cleaned up.
Good exposure and sharpness and you've captured a lovely interaction. Both birds' positions are great. I agree with James' comment that tilting your lens down just a bit, including more of the nest and less of the blank sky above would have made this very nice image even better.
