I think the first one is the most interesting, but I'm a little conflicted. Dragonflies are often a "pretty" subject, and I like the colors, but those eyes really stand out. It almost reminds me of an army helicopter? But it's still very interesting!
Cracking shots. Creeping up on dragonflys and getting a 'full-frontal' is not easy, so well done. #1 works the best for me. The dof in #2 is better but it doesn't seem as sharp.
