Well... yeah, there was no plot what-so-ever.

Didnt make any sense. There are a few things I did like about it though, the quality was very nice. Good picture, and very good sound. Thats really hard to do, and good sound is better than a good picture any day! So good job! Oh, and it moved at a really good pace! It kept moving like something was going to take place, which nothing did, but... whatever.
The knife in the wall where that guy is running past, was very quick and smooth.

So considering this was your "first film" i would say you did a very good job!

If you can make a feature or a decent short just like that with the good pacing, picture, and sound quality, it will turn out very good.
There is tons of crap out there from people who have gone to film school or havnt, its a lot of worthless stuff, but yours is good! Keep it up!
By the way, where are you going to film school?
