Hey Fernando,
I want to first say congrats on making your film. We all know how hard it is to just get into action and create what we set out to do. I watched your film a few times and I did enjoy it.
However, you did post this in the forum for feedback and I'm glad you did. I hope this can help you In some ways.
1.Please try to make your camera work mean something to the story not just production value. In the beginning of the picture you did a slow reveal move which was nice and then you kept doing it over and over. It's a wonderful camera move but, it has to be motivated for an audience who doesn't know the technique of filmmakimg to appreciate it.
2. Set. This is a tough one but the number one thing that makes this film not seem like a film is the backdrops the characters are placed in, perhaps you had this location available to you for free. My thought to you on this matter is, leave nothing the way it is, move the couch move the bed move everything around if you have to. Composition is important, and it's not only where you place the actors that matter in composition but,also where you place the objects in your frame. This is a tough one to wrap ones head around but, once you get it your life changes forever.
3. Read directing Actors by Judith Weston, you will not regret and If you have already, read it a lot more it saved my life and many other great filmmakers as well.
Once again Kudos to you!
