Very cool subject that is new to me. Lovely BG, but I see a couple dust spots begging for a quick cloning job (near subject's "shoulder," left edge a little below center). If you had backed up slightly my might of had enough DoF to cover the antennae, which seem slightly soft, and wouldn't be so tight/wouldn't have clipped bottom blossom.
Nice one Chris, so far they haven't appeared on my patch usually there are thousands. Tricky subject to photograph, the light angle is fairly critical. I think you have done an excellent job here, lovely exposure and composition, well done.
