I can certainly appreciate the effort and I think you're on your way to something special, and indeed a sad mood can be felt.
On the positive side I like it that you changed the viewpoint slightly, giving some balance between the left and the right picture with the white stream of the left picture being echoed in about the same place as the bright back of the fisherman of the right picture.
On the negative side the tone of the water and sky is quite different between the two pictures. It might be a conscious decision to PP the shots like that but to me it would work better if in the left picture the sky and water were the same darker tone as in the right picture.
Pls. take my comments with a grain of salt, I'm not an expert photo critic, but these were the first thoughts that came to my mind after looking at these pictures for a little while.
