I liked the camera work and the concept. Not an easy one to pull of well or make flow.
The acting to me was OK. What lacked was body language and a comfortable voice tone. They didn't seem relaxed, which makes their voices and body language flat. Expressions and movement communicate as much as the dialogue does to the audience. I think the sound issue has been thoroughly covered. I also think your lighting was better than most independent film makers, good job there. To conclude, always keep in mind what you are filming. People watch for the content (message, actors, etc.). It is the directors job to make the content as excellent as possible.
