Wonderful idea with the close up of the snail and in general I like this shot a lot. I might have tried a bit more DOF, but that is just a matter of taste here. This is a very nice shot. Good luck.
Thanks for the compliments! I would have liked to play a bit more with the DOF too, and perhaps get the second set of rings more in focus but I was running out of time and had to go somewhere.
Just wished I had taken more shots at different aperatures.
Still, I can have a play in my own time, although I need to find another subject as this one has disappeared!
