I somehow had a feeling when I heard your part that you would use that motorbike scene in HOTD. And it's nice. But perhaps playing around with some colouring to make it darker/night-time might help with the creepy mood. Oh and this.

Would definitely make it even more horror-esque.
I can't seem to view your beta for some reason. In MPC, it'll play the first 2 seconds then the rest is just darkness. In VLC, I can see the video but it's extremely blocky so I can't make out what's what. Though from the minimal bits I could actually see, it looks pretty good. Did you encode the beta in zarx? If so, I might need a .wmv version to view it properly.
