Iguana in a park

I would like opinions on this. I think this was the best of a series

of shots from these creatures in a park. In hindsight I only wish I

had opened more depth, to f/5.6 or f/8 perhaps. The distance wasn't

that war, but I still like the fact that the iguana is very clear,

while the unnecessary rocks are blurred. There were minor levels and

sharpening in PS. What do you think of the overall composition?

Thanks,
