Christopher, I love this image -- nice comp with the vertical boards and angled d'fly. I don't think you needed all of the left wings in the frame. Good choices with the sepia, and vignetting, although I think the vignette is a little stronger (more darkened) than necessary here.
Love the sepia...it's so well done, Christopher. I do wish the whole tail was in the frame but I'm not sure why - the comp is certainly interesting on its own.
I also think you could go up one more notch on the sharpening of the insect - the board below it looks sharper so I'd just add it to the body.
Thanks everyone! This was quite a departure from my usual dragonfly shots, which tend to be head-on; but I really liked how this comp turned out. Glad you all like it too!
