When I look at the image, I see that it is very obvious that the old man is thinking, or contemplating something. I also notice the detail on his clothing and even his face. The image seems calm and serene to me, which is what I believe the artist was going for. A piece that almost made you begin to contemplate water alongside the old man. Of course, this is all just my personal opinion. It's up to you for how this image makes you feel.
Hope this helps! : )
