Re: Landscape painting in Silhoette dilemma
Pay no attention to the photo! Paint the story you want to tell using paint!
All good stories have a primary subject and supporting characters and scenes. Determine what's truly important, and make whatever else may be included as secondary.
A sketch book for small thumbnail sketches, exploring composition and values is an excellent tool for all of this. Figure all of this out before you pick up a brush!
As for the photos, the green shapes at the top of the photo help to create a sense of depth for the photo, but may be completely unnecessary given the strong dominant shape of the church spire (assuming that's what's important for your painting).
You have selected a strong and appealing subject to paint. Good luck!
