Lovely light and wing position, head position. I agree with Joe, it is just a bit soft. How big of crop was this. I would think that your shutter speed would have been OK for a bird this size, but some folks push for higher when conditions allow. I suspect you didn't want to crank up your ISO anymore, however.
I am just starting to see some jagged edges along the leading wing, esp. the lower, so I don't think you could push the sharpening much more.
Hi Leo,
Maybe sharpen it a little more? I love these guys and you captured a fabulous banking move. I might have to go to Bushells Lagoon later today to see if I can get one. :D
