The green on this lil critter is so sharp and in such nice contrast to the browns on the stones..rocks..and the deep shadows that surround it..but I think that if you had taken this at a slightly different angle, and I know they come and go so fast that it's hard to capture them at the best of moments and angles, but if I were asking him to pose, I'd probably haven taken him a little more from the top so that I didn't lose that tail of his, but I can't complain..I've never had a macro of a dragonfly, much less one with so much clarity on the wings. Nice job ..superior take :)PJ
Your depth of field is rather shallow and the dragonfly could be a little brighter. I do like the wings and it is difficult to get good dof when the subject insists on moving.
