Managed to get this capture today, showing Lapwing landing on rocky beach.
It was pretty windy and you can see his tail is skewed as he comes in cross wind gusts.
Pretty large crop

Richard, you've got a nice in flight pose and a good HA; unfortunately, your crop has left quite a bit of noise throughtout the bird as well as some softness and loss of EQ. I'd back off the crop and see if you can get more of an environmental image with more of his surroundings included and see if that takes the lack of detail and noise more out of the picture.
Keep trying! You definitely managed to choose a good aperture and shutter speed so you're moving in the right direction!
