It's pretty good, actually. The very first cut is off -- her footsteps don't match from shot to shot. Same goes for the cut at :17 -- you gotta match those footsteps, and be precise.
The cut at :54 is pretty wonky. His position changes between shots, and it's clear that in one, he's slowing down from running, but in the other, he's completely stationary. When you shoot that footage, you need to shoot overlap. If you know you're going to cut from one shot to another, whatever is happening at the end of the first shot needs to also happen at the beginning of the next shot, and the performances need to match.
Those are the only three cuts that require any continuity, and they're all off. This is definitely an important thing to learn and practice. I don't say this to put you down, of course, but you're asking for critiques and my opinion is that continuity is something you should work on -- both in what you shoot, and in how you edit. For your next short, I think you should challenge yourself, and shoot and edit something that has nothing but continuous-action cuts, in which continuity needs to be adhered to.
As far as the content of the film, I think you did a nice job. It's easy to understand what's going on. The story makes perfect sense, and it flows just fine. To answer your question -- I don't think it's too fast, at all; it's too long. We get the idea pretty quickly, you can cut out some of that walking.
Best of luck on your next project. Cheers!
