I like this crop as well - the image has a bit of a retro feel for me and I dig it. The image would be even stronger for me though if the gestures of the fisherman were more in tandem. Lovely 'gestures' are like lipstick that make the face even prettier. (Can't believe I just wrote that - lol)
I'll admit I'm a softie on this...and I guess my eye just wants to see more love here because the scene looks romantic. If not more love, just more classic fishing positions.
In this case, from this angle, the woman looks more like she's walking through the scene instead of actively fishing.

I may have chosen to have the sharpest focus on the silhouettes instead here but this still works for me.

Just as an FYI - I too have 'spied' on people in this way waiting for the perfect gesture that may or may not happen....

Hope that may help and I'm very much enjoying these pix - hope to see more.
