"Island of Unfreedom". Level Design Blockout

Study work was completed as part of the XYZ Outblock course.
I called this level "Island of Unfreedom".
Location: somewhere in USA, present day.
Basic Conditions. 1. No mechanics 2. Gameplay is a run from one point to another. 3. Gameplay area is limited to a space of 80x80x80 meters. 4. A combination of open and closed spaces.
I used photos of Alcatraz and other old American prisons as a reference. I also used images from the movies The Shawshank Redemption, The Green Mile, Shutter Island.
