So I went back to the photo of the "Marji's Tree" painting--the one I'd taken before I added too much paint--and decided to crop it into a square shape. I think that helps. I do so love that flaming maple.
I ordered via Vistaprint some greeting cards of this scene, so we'll see how they look. Maybe this one will wind up in a pop-up shop someday soon.
Now, on to the next project.
