I like the pose and the dragonfly is well focused and sharp. I am guessing the square presentation was to minimise the foliage in the base? I like the image and think the exposure is good.
I think however, the Blacks are just a tiny bit heavy, and I may be tempted to soften or even brush the leaves beneath the tail and wing and the one far right.
For the most part I like this one, Stuart: nice light and BG, good sharpness/detail on your interesting subject. I just wish there weren't shadows on the face and abdomen. I reflector to your right could have helped with that, although I realize you well may not have had the time or the arms to do that.
