More great shots, Don.
I love the first. It has an hdr look to it. I guess it is rare to see a shot with a perfectly exposed sky *and* ground. Did you use a graduated filter in post processing?
I also love the last one. I've seen (and taken) a lot of dragonfly shots, but I don't think I've seen one from that angle, with the head visible through the wing. Plus I love the contrast between the smooth green background and the texture of the twig (or whatever thing it is perched on).
