Interesting start! Noticed the comments on Steam about the trailer being overly dark, so won't rehash here. Looking forward to seeing more.
One thing I will note is that the font choices in the trailer are a bit odd, and detract from the overall vibe. You could probably find creepier/more classic fonts, rather than the highly modern humanist ones being used.
As well, I'd recommend editing the logos to fit the dark background, rather than adding a light glow around dark logos on a dark background. I've attached the appropriate Leap Motion logo in PNG format below; you could make the Oculus and Vive logos white.
