It is a nice image Dave but if you don't mind I will offer a suggestion. Post processing of this image could improve it. I suggest just a tad more contrast which will brighten it some and give the appearance of being sharper. Love the use of DOF to isolate this lovely Blue Dasher.
Love the background colors and the picture in general. If you're gonna clone out the bottom left flower, try cropping the stem of the main flower too. I did using the scroll bar in this window and Gale's right, it looks like a greeting card!
