Mars base Inside Victoria Crater

This is my interpretation of a martian base for human living and research.
It is intended to be built inside the Victoria Crater. This crater has a relatively small size and it has a flat surface inside wich makes it good for protection and construction.
The kit/base comes with:

Observation and research room
Water and supplies room
Common room
Oxygen and gas station
Transportation area with 2 vehicles.
Sanitary Area
Entertainment from earth (TV Shows) and Fitness room
