Your timing was excellent, like the small angle of bird towards us, shows both wings well. The flipped up tail feathers nice as well
The image looks a bit overexposed to me. The whites on the rump are in the 250 range and aren't showing much detail.
I would suggest returning to the raw file and see if you can reprocess is with the intention of lowering the exposure enough to save the whites. Not always possible, but worth a check.
