I'm sorry but this wasn't really good. The biggest problem is that I couldn't understand a word the characters were saying (because of the bad mics), so I dont even know if there were jokes.
That can be easily solved by adding subtitles.
The second problem is the lack of music or sound effects. Every shot has to have some sort of sound or it just feels wierd.
The writing was mostly meh (from what I could tell), and relied too much on cliches.
One thing that did make me smile was the floating gag at 1:09.
I'm sorry if I came off harsh in this, I'm not trying to offend, but I think you can do a lot better.
