I saw someone in the tag post something similar, But I have never seen this setup seen at this angle before anywhere so I took a try at it. Its really rough and crappy but eh.
the lighter brown represents sediment that has settled since he crashed, the darker brown is the bedrock layer he left a crater in/ the chunks of rock that settled on top of him (as shown in the rising video), the blue ovals are domes and the red one is the core. Obviously his torso would have other spaces and access tubes and machinery but this is a diagram, not a schematic. Everything else is labeled accordingly.
