a great moment you've captured but I would say 1) too pixelated, 2) barely any pan and 3) too zoomed out for an action shot of this sort... and I know its a pain I can only go to 200mm myself! I think if this were cropped into just the bird and the reflection it would be a standout shot, even if the bird is facing outwards
It's a nicely timed shot, but there's minimal signs of any panning going on. It would have been nice to see some horizontal streaking of the background.
I love the capture of this moment in time. The processing doesn't work for me, and I see little to no tale-tale streaks that indicate motion panning. This looks more like stopped motion except for the trees. This tells me your shutter speed was too short to look like motion panning.
