Thank you David, Eric and Jeremy,
I appreciate the comments. Don't really know what to do (if anything) about the wing. I tried a version with it cropped out but that was very unbalanced, decided to leave it as a leading element but I understand your view. I'm still trying to get the hang of macro work, it's pretty easy with flowers or stationary objects but moving targets are a challenge for me.
Particularly, given the focal length you were using, from a long way away! Keep at it - I am trying to get the hang of macro work and am finding it jolly difficult.
