You could not have said it better!
Personally, I really enjoyed her comics and when I found out about her patreon are her extra content I really felt like I had found some hidden treasure or something lol
So many people see her comics through different medias, especially reddit, but how many of these people know about that side of her? It just makes it feel that much more exclusive.
And as you mentioned, she really is "average" looking on the surface if you compare her to mainstream models, but considering the whole thing with her comics and the way she promotes her content makes her exponentially more attractive and sexy. It feels a lot more genuine and authentic.
