Thanks for the comments. This is a crop. When I was playing with the cropping I had to choose whether to make it a little looser which would have included more of the nice pattern around the eye, but it also would have included background. Above the eye fell out of focus very quickly and seemed more distracting than interesting, but I was mainly trying to include just the critter in the crop which is why I made it tighter. I've been playing around with a 'patterns in nature' series, so I went with the macro-type crop. I agree that the placement of the eye does make you want it to be more in the frame. Sigh.

I'll ID the critter later, just in case anyone else wants to hazard a guess. Turtle? I can see that, but, no, its not a turtle.

Oh, Jim, I agree with you about the focus. Full frame, 2.8 100mm Macro lens. Razor thin DOF. Unrestrained, roving critter.
