Hello,
The young lady in the link you provided is charming... I watched some of her videos! I do love her minimal use of makeup (which I also prefer), and admire her openness. However, this approach--specifically, showing her face--is definitely not something I am comfortable doing.
I currently have 2 videos up on my website, and while they are definitely "polished" (I hope) and with music, I do think they capture a bit of my personality, which is what I wanted to offer. Obviously I wanted to show off my body as well.

I like to think that certain details in my videos express my playfulness, while viewers can hopefully also get a sense of my style, sensuality, and very laid back demeanor.
Despite my own preferences, I can totally understand your preference for a more "simple self made production." For me, I was planning to post all "selfie" photos/video on my new twitter account, however now I will absolutely consider posting the informal, self-made stuff to my website as well.
I'm honestly glad to have read your take on provider videos.... it's good to know that the self-made productions can be enjoyed & appreciated a great deal.
Thanks for bringing up this topic!
xo, Mia
