A wonderful macro, with gorgeous light, beautifully captured, providing nice highlights... The black background also contributes to the fine composition... The only thing lacking, in my opinion, is the crystal clarity of the subject that is important when shooting a macro like this. Perhaps a greater depth of field would have captured more detail in the shell, but I have a hunch you could even bring added sharpness with careful use of a sharpening tool in an editing program like Photoshop. Very nice work.
