I don't like the blue. But hey if thats the worst i can come up with you did a great job. Everything else looks perfect. But feel the blue is to stron and pulls away from the great testure on the snail.
What a neat shot! It's a great macro - the snail is in great focus, the shell shows texture very well. I only have one complaint. The bar/pole/brown object in the background. My eye started at the shell and moved left, only to be distracted by the pole when it got there.
