Nicely done, Frank. The light contrast makes the shot quite dramatic. As for the composition, I think the shot would have looked better by having more space in the direction they're facing. I would have cropped off 2/3 of the bottom and 75% of the right. The result would look sort of like this.
Rog has given some good advice here Frank, I really like the effect you got from the rippled water, makes for some good lines in this shot. Tigs♥ =^..^=
