Wow, what I love most about this are the two splashes created by the wings...very cool! You could crop about half the bottom and half the right...the strong water trail coming diagonally down from ULC would justify placing the bird closer to right edge and also help emphasize to powerful oncoming action. Just a thought. Highly enjoyable photograph as is anyhow :-)
Love the straight on take-off you captured Grace and as Fab already mentioned great focal pont on the head, Well done and big congratulations. Love it.
