First off, having Gerard Butler in your movie gives it a lot of credibility.
Okay, I only bring this up, because I was looking at your profile info and saw that you listed LAW ABIDING CITIZEN as one of your favorite films. I thought, "wait a minute..."
Good enough to be a stand in, right?
Okay, on to your short. Good title, which makes this all relevant. For a first short, this wasn't bad. You even had some nice aerials. I think this should have been cut down, in parts - like one cut to the face on the pillow, instead of two. I thought that was a fairly well composed shot, in spite of the auto-focus kicking in and out.
If you were to make this again, I would suggest more of a rapport with the dog. There was a lot of unrealized potential there.
Though far from perfect, I have to hand it to you; you made this by yourself and it worked fairly well. The melancholy mood of being alone (almost alone) during Christmas. That is something most people can relate to.
Don't have too much fun doing this, otherwise, you won't be able to stop; and pretty soon people will start throwing that other "F" word around, to describe you.
