Practice, Practice, Practice!

I probably have more photos of myself than anyone in my own family.  Here, I was testing a portable lighting setup which uses a Nikon SB800 flash, mounted on a light stand, and a shoot-through umbrella with black backing.  The umbrella was only a couple feet away using about 1/8th power.  The advantage of shooting low power like this is that the batteries will run all day.  I shot this with my old trusty D80 at ISO 200, 1/100 sec to control light on the backdrop, with aperture set at f/7.1.

Tim, does this qualify as "fierce"?
