Older walls, like the one pictured above would have a nostalgic feeling of tattered industrialization. The other walls with tree shadows, I imagine them to be cleaner cut, more contemporary-looking. The tree shadow could represent the shadow of nature on contemporary society, meaning it still touches it, but it doesn't seem to make a huge difference. Maybe, maybe not. I also just thought that I could do some cool color palettes with the oil paints.
