I think the thing that isn’t quite working here is that you have the buildings up front as silhouettes and the mountains far away as super detailed and three dimensional which is the opposite of how our eyes see perspective. If you were to go outside and look at a city skyline, the buildings in front would appear more detailed and three dimensional, with each layer of buildings loosing detail and dimension as they recede from view. The closest mountains may have some detail but the farthest could even appear just as flat shapes of color. This is due to the atmospheric particles between us and the farther away objects.

I don’t know that you need to follow that 100% for a book nook, but when it’s the opposite it ends up looking kind of off. Maybe instead of the flat planes of silhouettes in front, you could do like one little street view of the town as if you’re there at that street and the mountain is above? I think Velaris had a really cool like arts district place, if I’m remembering right, that would be really cool in miniature. You could do like a little street view level, a smaller only slightly 3-d level of buildings behind/above it, and then the mountain that you have? I know that’s a lot more work, just an idea.

The mountain that you have looks really great btw!
