No, I don't believe it's chopped.
1) Left girl, her leg is blured but I think it's cause by shutter speed. She could have move a little when the pic was taken.
2) Light is off, at falls like this lighting could play a trick.
But what really makes it a non chop is the noise. If U look closely the girl and the background seem to match up pretty well.
Just my 0.254cents opinion.
But what should be very critical and most important is......Just enjoy the pic. 2 nice chics giving smile to the camera. A good smile is not possible to chop.
