One easy way to not try to say too much in one painting is to crop out what is not essential to tell the story. This allows the viewers to focus on only a few elements. Successful still life artists know this all too well. Too many objects will make the painting busy. Nothing changes in this regard to landscapes.
Think of your rectangular canvas format like the square feet of your home. You want to make the best out of that limited space but not clutter things. I recommend you try to crop your photo several ways until you feel you have the right version. Most of the time, I find that zooming in ends up being the best policy as long as you don’t suffocate the scene. Here you will need to rely on artistic asthetics and just follow your instincts on what to include or leave out.
In the top photo, there are two boats and several houses competing for attention. There is too much water and the stones with the bushes on the left will not add this to composition at all. After cropping and trying several alternatives, I ended up with the second picture that had enough of the information I needed to tell the story.
