Nice study. For myself, i would have toned down that edge of the leaf with some careful brush-work, and perhaps played with trying to bring the background exposure down some ... just to force the eye toward the snail that bit more strongly (those patterns and shapes there are maybe a bit too present?). Light and detail on the snail are great, the overall crop is spot-on to emphasise the location. Strong work, and those reservations really are passing thoughts only. Well done indeed.
Excellent rendering. The light is wonderful and really makes this picture special (especially the light on the leaf edge). Who'd think a snail could be such a winner. Superb macro capture.
