I would try selectively burning some of the darker areas of the wings (no more than 5-6%). A bit of work is needed on the eye too. Other than than this is a tremendous, and not easy to achieve, photograph. Very cool!
Thank you all for the excellent suggestions ... and they should be pretty easy to do!:)
I have to pause here to say that I can really feel the improvements with each post, and have learned so much from all of you in only a few months time! I'll get off the soapbox now ... thanks!
