Hey John,
Does appear to me also that a bit of CW rotation may be in order.......but you captured sweet wing details and the BG color is very complimentary. A lower angle as Axel recommended may have helped blur/soften it even more........but not sure what else that may have introduced. Sweet light and you captured a really nice wing position.
Thank you both for the feedback. Completely agree that a lower angle would be better. It's difficult to do that at this location as one needs to photograph from an elevated platform and as some railings are in the way.
