Lighting the subject--dark and mysterious

Playing with light tonight. I had a Pentax 540 camera left sitting on floor 45 degrees. I started at 1/16 power but did not have enough umph so I cranked to 1/8 power. Hairlight directly behind subject at full power, also a 540 flash both triggered with my pocket wizards. Played with different poses and it came down to this dorky shot.
