Nice demo.
Just one question. Is 1.440x900 out for something or you just forgot it?
Most 19" wide use that resolution (and when my FPS are low, I use too with my 20" 1.680x1.050 because both are 16:10).
PD. You could try something more "cinematic". Something like a cript, moon lighted with fog floowing from a litte window. Fade to dark and then lighted with just one big stained-glass lamp.
