Holy smokes - that's a tough shot! Well done! (I've been capturing some dragonflys recently myself.) I like the bokeh behind the subject too, good complement.
Wow. You even captured the patterns in the wings. Nicely done. Still feels a little bit soft, and a little noisy. An interesting crop, makes me wonder what the rest of that hint you've left in the bottom left is? ;^) This was advanced...could have cloned that little piece out. Just a thought. Good luck in the challenge.
