I agree that model should be totally seen in video. For instance in Roman Lidia's videos the full length of her hair can not be seen. Filming distance should be so that model and hair can be fully seen.

And I would like to see model doing normal stuff and not trying to present hair. For instance in Alesta videos there are many times this other lady making fun on Alesta's hair. I do not know is it just me but I like most videos where only the long hair model is.
