Dutch angle shot

Today the assignment on Digital Photography School was to do a "dutch angle shot".  These are shots taken at an angle to give a somewhat mysterious (film noir-ish) look.  Think Hitchcock...  Here is my first attempt at doing this.  I'd like to play around with this some more to figure out the best angle.  I also think shooting it from a lower perspective would increase the effect.  This was shot at 10mm (cropped body) f3.5 1/25 sec.
