Negative and Positive?

That is a great set-up, however as other people have mentioned the lighting doesn't look quite right. Because of atmospheric perspective, distant objects often appear lighter and feature less colour. This might be why your diorama feels unbalanced, the backdrop is to dark.

Interesting point. In retrospect I had trouble deciding what time of day I wanted (morning, day, evening) and a corresponding atmospheric condition. My indecisiveness is showing through.
