Not bad
But you need to work on your director's skills. Especially with a movie file, you have too many scenes with serious amounts of wasted moments. Seing 5 seconds of someone's back is a BIG deal in an actual movie, it's pretty deadly in a situation like this.
You need to speed things up. The computer scene needed .5 seconds of sitting down, maybe a closeup of the computer, or searching throught the HD. The scene where the stick "surprised" you on the staircase? The viewer should either be surprised as well, or anticipating something.
keep working on it.
