yes well done, that looks like it keyed out nicely.
On the white balance note. If i get some Fluorescents to light the screen, but then just a small clamp lamp for adding a little light to the subjects face. Would it matter if the little light for the subject was Tungsten? Im guessing Fluorescent would be preferable just to keep everything the same, but seems like since your keying out the screen anyways the color discrepancy wouldn't matter?
