Can I call gimmick?
If an artists sees more of you, such as in a video, he/she gets a sense of your personality (are you funny? dark? or perhaps in your case, cynical?) and can put a little more of that into the artwork.
Doing it asynchronously seems to be so advantageous. Can it not be done without sacrificing quality?
So Diy video, ok, face time, better, recorded videoconference, best.
