'What If?' Metropolis: Thumbnails 13-15

With #13 I tried to illustrate the concept of caves described in my travelogue and how their walls are covered with pattern-like paintings, reminiscent of Day's earliest creations.
#15 is an exaggerated/overly dramatic version of a composition if I were to put the two worlds in the same frame — in other words, not something I plan to use as my final painting!
