hmmm, I don't know if it was moving as fast as you said it was. I thought the picture taking thing was interesting, but after a while the sound just got annoying to hear, it felt overused.
also, while it was unigue you had the whole thing in black/white I also felt it was unnecessary, for me it didn't add anything to the vibe and I felt like I was watching a flaskback the whole time.
Like the person above did say, it is good you worked with what you had, but the story was a bit of an apparition...it felt predictable(once I figured out there was a killer, I knew it killed her and was coming for the guys;when they answered the phone you knew they were about to get killed.)
Also, like Fash said the Weezer song was way out of place for the end of the movie, you want to carry on the feeling not execute it.
I though the color thing(unless that's what topography is) was an interesting choice for death signal rather than blood.
Lastly, it could just be me, but is your audio not synched up, I could've sworn when people were talking they mouthed after they voiced things.
