Tis film was a bit confusing. Actors changed (I think). and characters seemed to alter. Continuity was a huge issue as clothing kept switching. I went back a couple of times just to confirm. Story was a bit confusing. Edits were disjointed and camera work was very shaky and unfocused. Music was good and did set mood as did lighting. Exteriors were well shot.

Color Correct - keep consistent throughout
Audio - Balance
Make sure you use a tripod or steady cam -

I like the outside of the hotel locations -

This is a well written story. Unfortunately due to the actress being sick, main character had to change.

Good Story, Nice Flow, But the technical side needs work. Use a tripod when available. a lot of tracking shots that were very very shaky and distracting. Steadicams and tracking software can help clean this up. The audio had some low spots. The use of practical lighting adds a nice touch but consider how you motivate them within your scene at the end

With suspense/thrillers, sound is extremely important. I really liked some of the sound design. I got pretty lost in the story as soon as the girl from the parking garage suddenly, and without reason, vanished from the story. The bold color choice at the end was a nice emotional touch.
