Does anyone know any good art tutorials on youtube or the such that do more of the basics?

I mean like when I was a kid they use to sell books that took you through drawing just one xmen character from start to finish, first it went through a few pages of how to do the skeleton, than fleshing it out, coloring, etc....

I have been unable to find anything in regards to teaching like this anymore. When I try to find some art tutorials they are either the basics of artistic painting or such. Which is very useful, but not the direction I am looking for.

If I try to look for comic book, or manga tutorials they do not show the skeleton aspect which is what I want to start with. Any ideas would be appreciated.
