As I mentioned before the movable engine going through the heat shield is a huge safety concern. However, there’s plenty of smaller oddities as well.

For one thing, pilot position is wrong. Here’s the whiteboard sketch:

A better view would be to turn it so the acceleration line is vertical:

Note that they did all the tricks with the engine especially in order to keep the acceleration vector pointing in the same direction at all flight modes. But the correct body position for the pilot to withstand 8G is with knees just a bit below the head:

Another odd thing I noticed was the location of the RCS thrusters in the nose. The Mangosteen is so damn small, that it’s simply impossible. Even far bigger capsules group thrusters near their fuel tanks. Here’s an example of SpaceX Dragon:
