I like the simple yet elegant composition of this photo. There does seem to be some noise in the sky which is slightly distracting to me, and it looks as though the dragonfly may be slightly oversharpened. Good job managing to capture one of these guys on the fly!
Great capture of stop motion. Seeing some fringing around the grass blade, and I wish the blue was a little darker (just my preference I know) - but otherwise a nice catch here. Good luck.
