Not bad at all. I'd try a few things though. Make sure you have motion blur on (I can't tell for sure if it's on or off from the flash video, but it looks like it's not). Also, I'd play with the camera movement a bit. You might want to make the camera quickly whip-pan from the wall to the floor to hide the corner of the two planes (the corner is the biggest thing that detracts from the realism for me). And I'd play with the camera's bezier handles a little bit to make the camera motion smoother. You're off to a solid start!
