There's some nice stuff here.
I think I would've liked it better if it was edited to 3/4 of its length or even less.
Her reactions after the elevators seem a bit slow, maybe those shots can be cut down.
Maybe for your next one you can tell your actor to speed things up a bit.
Good effort, good luck with it.
