this looks interesting and I will watch the entire course, but from a quick look I’m seeing it defines “virtual beauty” with “normal people” which is a big fail.
There is a reason why big Hollywood stars are either “god like beautiful” or “out of ordinary/strange like people”, because people “want” the “best” or “something that intrigues”.
In games we want the “super man” or “super woman”. Making the hero of the game “normal looking” is a chance for disaster. Occasionally you may want to subvert the expectations, fine, but if you want to increase chances for a “blockbuster” you need to follow these rules if one likes it or not.
Examples are numerous, but just to take one, the game Tekken has both of these archetypes, “quirk interesting characters” and “beautiful” characters.
Please don’t take this a criticism against the people featured in the course, we all are “normal” people like them 
, “Hollywood stars” are just that, a limited number of people we will never have contact with.
