Great composition. The way you have the subject arrange helps to lead your eyes from the head toward the bottom where the claws are just it much interest. Excellent depth of field also helps.
A little tight on top. There seems to be a shadow in the water in front too that almost looks like a camera. Just a little tiny bit out of focus. Otherwise, not too bad
Nicely done, would like to see a bit morelight in the lower left. Great "expression" - if that's the right term - on your subject. Would like to see his nearer legs in focus
