I love the comp, exposure, blend of greens and especially the eye contact in this one Alfred...he/she definitely does look a bit forlorn and maybe even embarrassed about his/her condition. Seems to be missing a couple of toes on the right foot as well!
A very nice natural history image, Alfred and it does look rather unhappy. :) Sharp, good exposure and nice lighting. The only thing I'm not that fond of is the catchlight in the lower portion of the eye - looks a bit odd to me. If this is a flash-generated catchlight, I would suggest moving it to the upper third of the pupil. Minor point - there are a few dust spots evident in the OOF background area. Overall, well done.
Poor fellow! I'd be in hiding, too, if I looked like that!
Alfred, this is a wonderful example of why one would buy a macro lens! Perfect DOF and right where you want it to be. Nice BG and composition is perfect.
