What If? Metropolis - Library Design

I created this thumbnail using the silhouettes and 3D models I have made. I like the design and I think it matches the other buildings but still looks more elaborate than the others. It is less textured just because of the type of brush I used, but I plan on adding more texture to the library in my final concept painting. For this thumbnail, I just wanted to get down the basic shapes and not worry so much about the texture yet. I might take this into maya and/or Illustrator later on to help me get a better idea of the shapes and how it would look from different perspectives.
