In this very busy image you've done two things to simplify - narrow DOF to blurr the background and isolate the subject, and desaturate to draw attention. But my eyes are draw two ways - the bright desaturated flower - and then the dragon fly which is not at first apparent. I think desaturating the dragon fly would work better - or desaturate all the plant life - show how plant and animal life are different...
messy composition. Need to think what you are trying to show, what the subject is. I see a distracting background, a damselfly facing sideways, a messy flower. Subject totally unclear to me and no impact.
At least on my monitor, this is pretty dark. I am afraid I am losing the significance of the various elements in the picture. It is vry busy and gives my eye no place to rest.
