NoWayMe hit on a very important note. The real benefit of the videos is watching them and doing the work in them. First try what the artist/teacher is doing in the video, then try to make it your own. I would say you could maybe do 1 video a month if you were really motivated.
Watching a lot of the videos back to back may seem like education, but it rarely creates lasting effects on the work. I equate it to "entertainment" more than education if you aren't doing the work that is suggested in the videos.
We are also moving to a more interactive type class and I'm currently running the 2nd term of my 10 week illustration class with David Hohn teaching as well. Will is getting ready to start a live class and we have a lot more videos coming out soon too. Should keep you busy for a while! : )
