For my preferences if you had cropped the right side just past the pier posts this would keep my interest in people longer as the whiteness of water leads me out of photo.
So which one is George? Just kidding. I love the composition of this, and the expressions on both the subjects is quite telling. We've all been there. Great backdrop as well.
I'd probably go for a close crop. It's hard to crop in on the subject when you have such an interesting background though, but I think it would improve the real image. :)
