Very nice. The graphics look very nice and clear, the movement is very smooth, and I especially like how your dynamic shadows work. The only problems I noticed is a somewhat long loading time, and the chair in on of the rooms changes to black some times (same as Sledge's screenshot, but with the chair).
My specs are:
AMD Anthlon 64 3700
1GB RAM
GeForce 7800 GT
Windows XP Home
