Making a Christmas painting for my mom inspired by the below photo.

It is still very much a work in progress. I’ve decided I don’t like the tree in the background. I plan to paint over it and I’m looking for advice on what to put there instead that will balance the colors and composition.

Current ideas include a window with some kind of snow scene, or just make it a red wall, maybe with a vague wallpaper pattern.

Thanks in advance for any suggestions or feedback.
