Excellent shot. Very nice color and subject isolation. However, one of the prettiest things about dragons are the wings, and there's just not enough wing in focus here.
Very nicely done on the details and colors, but the overall composition lacks interest and does not hold my attention. Framing the line that runs from wingtip to wingtip, through the eyes, slighly higher in the frame would have provided a sense of motion to the image.
Really beautiful colors, makes me feel happy just to look at it!. It's too bad that more of the dragon fly isn't in focus but it's lovely just the way it is.
It's too bad the dragonfly wasn't a little sharper. Other than that I like the pose and the flower it is standing on. The big purple flowers in the background adds some nice colour too. Good job.
