We are doing something similar when we paint. The many features of our subject present themselves, all jostling one another for the spotlight. To know better what needs to be in the picture and what is optional, it helps to decide what the important thing is to you.
Find an image that appeals to you and take time to identify what you want to focus on in the scene. This is not necessarily a "focal point", or a center of interest. It may be a feeling, rather than a particular spot on the page. Keep it in mind when you make decisions about palette, cropping, how the page is oriented, which shapes need to be separated and which combined...everything, in other words.
When we put them up on the wall next week, we can try guessing what the important thing was to you.
