Breaking the rules of headshots

My lovely wife wanted some new headshots and asked if we could try to get some good photos.  I've recently been thinking about trying white on white or black on black portraits, even though that's sort of a cardinal sin.

With that in mind, I figure that rules were meant to be broken, as long as the result is worth it:

I used two softboxes as key lights, a 4x3 from above pointed down at an angle, and a 1x3 pointed up from below.  There was a strobe with an umbrella behind the white paper backdrop, with the light bouncing off the wall directly behind it, just like my Vogue Italia shot.

Shot on my 5d3 with an 85mm at f3.2, 1/40, and (I think) ISO 100.

What do you think?
