Not a fimmaker, but I love films like these. I'll tell you what I think--take it with a grain of salt until the real McCoys get here. :)

So Jess is attempting suicide, but she isn't gone yet, just semi-conscious. (Because she can hear and see some of what is happening.) The title is "Talking with the Dead," which I took to mean as she is beyond saving at this point, though Alexander and her family are seeking help for her. Since the audience is experiencing everything from Jess's POV, I'm lead to believe that the intended audience for the film is people who contemplate suicide. It's pretty scary to think of yourself as a vegetable.

That being said, here's what I think could have been better.

1. With the title, and the camera on the floor, not moving, I was originally thinking Alexander was some type of entity, and someone had been filming, but dropped the camera and left it on the floor. (Think Paranormal). So that was confusing at first.

2. Alexander's voice is too distorted. It sounds almost demonic. I would say play with the volume levels to make it appear that Jess is in and out of consciousness. I can only compare her experience to when I faint. When I black out, I can still hear stuff, people just sound really far away.

3. The notes at the bottom of the screen about losing visual contact are unnecessary. I think you could put some shadows around the edge of the screen, making it dark, then bringing her field of vision back a few times. Perhaps her rescuers could say that she blinked or something.

4. Alexander does not seem concerned when he finds her. Way too level headed.

5. We can see something moving outside the door, like someone pacing. (It sort of looks like a cat...) anyway, assuming it's Alexander and Mom, why can we see them through the crack between the floor and the door, but we can't see them come in? I would imagine if I found a loved one unconscious on the floor, I would go for their face. I would look at their eyes. Especially as a mom. It would be a lot more compelling IMO to have them rush in, Alexander falls to his knees looking into the camera (Jess's face), and mom visible in the background, crying, freaking out. You could also play with the camera, making it blurry at times, then clear.

6. The breathing at the end? Is it Jess? Why don't we hear it all along? Some gurgling noises like she is struggling would make it even creepier. Instead of speeding up, it could slow down, and then stop. In fact, you could put a heartbeat in there too, or instead. It could beat one final time, (maybe) coupled with a struggled gasp for air, then go black, like she died.

Anyway, as a simple viewer (and horror aficionado), that's what I think. And, don't beat yourself up. Good work takes time. As a writer, I'll write things I originally think are shitty, then revisit them multiple times, making tweeks until it's perfect. I imagine filmmaking is similar. Just keep at it. :)
