GR view missing. Why does MP have 3 exits? I would consider corridor to TS an illegal dead end. No control of CR. Can't tell if you have control of GR or main entry. Why does SO have 2 doors? Why does LM have 2 doors?
...and... Double doors are a waste of time. Egress capacity is not in the scope of this vignette. The exterior exit near the east stair is redundant. TR's do not have to stack.
