I'm going to be brutally honest.
I'm guessing you're young. From what I've seen, I would think you're a photographer first, and film maker second. You have a great eye for content, but not so much (from my weak brain) for storytelling.
Here's where my weak brain comes in; The first two minutes are pan shots of a piano, chair, dolls, clock... If there's meaning to these, I can't figure it out. While each inanimate object was very pretty, and well kept. The (after the first two) annoying pans had me bored. However, if these were still photographs of the objects, a viewer would probably be more interested. You frame everything beautifully.
The actors unfortunately were awful. But, I expected that. Directing good and bad actors is one of the hardest talents to master. You can't just do it. The director has to know exactly what each character is feeling at the exact moment of each shot. The director then has to convey that to the actor, who lives it in front of the camera. 90% of young people don't know their own feelings, let alone emotions of a fictional character.
There were a few poor edits, the biggest being the beating with the bat. You left in the fact the guy was beating the door and not the kid. Even if you didn't have a decent angled shot of the bat coming down, cut quicker, and use sound effects. You used sound really well. Leaving these bad shots in, destroys any effect the beating could have had.
This could be way shorter then 9 minutes. The pans, oh the pans. I want to seriously break that dolly thing you used. Seriously.
If you're young, you did a great job. If you're my age, and new at it, great job. If you're my age and been planning this out for a real long time, not so much.
What you might want to do is, be a Director of Photography for a while. You have the talent to shoot a movie (if that was you behind the camera). But, the experience of working with people who actually direct could help you immeasurably.
