I think it was very unsettling, and agree that the visuals are great. I particularly liked the overlay with the eyes flashing, and the way you used a bulge effect in places. Reminded me at times of Hausu.
Also going to second that font choice. It either has to be larger, or a more basic font. Perhaps there could be less flickering in the background while the text is up to help with readability.
Maybe a bit long for a trailer, but it works well as a short.
And of course, if anything comes of this, make sure you find some music and sound effects that aren't copyrighted.
