Hi Joe, the head is an improvement and perhaps in my own interpretation my thoughts on colour are to way off and punchy, I'm guessing not being there.
You know my thoughts on the workflow, so I think it would be hard to do much more, however perhaps brushing the Iris adjustment over the wings may bring ou more of the iridescent colour, but again I don't know if there colourful or a more drab black????
Hope my email made sense and clarification of some of your points??? Sharpening looks better, did you address any settings now?
Just a thought, but how about a 16x10 crop, so you loose a fraction off the bottom?
