I think there are always two ways to look at a picture, the capture and the technical execution.
Personally if the capture is good enough Im happy. You caught a great moment in time, the picture is interesting, keeps me looking for more in it.
Technically I am very inexperienced, but my gut says 1 -cutting the head is a pity, and indeed as has been said the girls are distracting slightly.
Someone mentioned earlier, I say shoot the moment first, capture it. for me the technical execution comes 2nd.
Really nice picture.
