Scifi Tower Complex

This is a simple idea for an atmospheric processing tower. I wanted to do a strong, simple and monolith silhouette and from there work on the feeling of size though perspective, atmospheric depth and some detailing. I play with different designs and with the idea of attaching a research facility in the structure, adding in complexity and size or having it half collapsed and abandoned due to some cataclysmic event.
