PS -- one thought (in mentor role)...there is a lot of black shadow on the left. What would have happened if you'd cropped off some of the far left, and then a little of the top and bottom to balance it out?
Well done to you, it is so difficult to capture birds in flight, you just get focused on one and it veers off, doesn't matter how hard you try to lock on.
Hoorah, could this be the start of something big?
