Yeah, this is awesome.
Really great job with this one, it's got a ton of atmosphere, and the composition of the different shots are well thought out. The artwork is awesome, especially the outside of the mansion, but you do a good job not showing it for longer than you need to, keeping the 'flow' going. If I had to make one (tiny) complaint it'd be that the music stays sort of light and happy, even when the kids start dying, killing the drama just a bit. Though this gives it more of a 'music video' feel, maybe what you were going for...also the muted music during the bathroom scene was a good touch.
Really great title screen, too.
