Very nice Stu, scene is very well lit, and processed as always. Like the way the light seems to shine through the wings, illuminating them in that way. Great work
Re: the technical aspects, I'm surprised somewhat by the high ISO. I would've thought somewhere around the 200 mark would have been plenty but perhaps it was darker than I thought when you took it? As for the shutter speed, sensational - 1/2500 if ya don't mind! :)
