The heron itself looks great, but I find the surroundings quite dirty. Although a lower angle would have normally been better, here it would have placed the close and busy mangrove BG directly behind the bird so I am OK with this. I do wish for more room below the feet however.
Thanks for the comments Daniel. I cropped off part of the lower section so I can
add more to the feet. Would you recommend getting rid of those white shell
fragments to give a more uniform base?
I like the sharpness and walking pose and would put the bird a bit higher in the frame. I don't find the shells distracting but removing them would be an option.
