Looks like you and I are working on very similar concepts. I'm still in the building stages of mine...getting rough models together to place in the scene to get some lighting effects down. Scary bedroom....scary lights...figure in the window. I'm still real new to Maya so it will take me a while to get mine done....but I really like what you've come up with so far.

Did you use text effects to get those letters on the blocks and dresser or did you manually extrude them? I like the curtain effects you have too. I havent gotten to my curtains yet I was waiting to complete a tutorial on cloth and using forces.

Super shadow effect on the floor! Great idea.
