Dibujos sin Papel: Plaster Cast

For the stereotmic map I decided to focus on the the three walls and the excavated space inbetween. The first try I cast so that the walls protruded outward. Some of the issues were that the walls were delicate and the mold was difficult to unmold.

In the second try, I reversed the cast by having the walls sunk in and the land raised. I am unsure as to how I feel about the heights of the land and if the walls need to be carved in more. I also think there may be a better way to frame the cast.
