Really nice shot. I think the lighting is a little harsh (making everything a little washed out), but you've got great DOF and the detail on the wings is excellent. Great composition too. Nice job.
Very nice DOF. Lighting is perfect. Good texture on the wings, but the background maybe just a tad too busy and distracts a little. I bet that desaturating some of the color (green and yellow?) in the background would help.
