Overall very strong shot with good colours. The background noise is a little distracting, however, and it seems to have been amplified by excessive sharpening - there is also a sharpening halo around the edge of the eye on the left.
We were bombarded with these guys in the summer of 2015 so I was busy taking lots of pictures too. They are quite patient little things (or maybe they're just still because they're playing dead?) with a most interesting array of colours and markings. I'm very glad they aren't any larger, they have decidedly nasty looking chompers. Anyways, great composition, colours and focus!
