Really tricky one to comment on as I know how hard it is to get a good shot. But in a perfect world the flower in the foreground is distracting. A little more depth of field may have been nicer to get both wings in focus, so a bit narrower than f4 as unless it was a very windy day I don't think you really need 1/1,250 sec. You can't really see that much of the bee either. Saying that it is still a good shot.
