I didn't make this tutorial seriously, as in that it's one that people should follow. one thing I found interesting was that as I was making it, I was able to spot mistakes I was making a lot faster and could understand what to do about them better this way, than if I were to draw a bunch of heads without my own tutorial. my suggestion is try it, with what ever you're having problems understanding, like how to draw hands, or other stuff that I can't think of right now. the way I see it, it's not so much making a tutorial for others to see, but more taking notes for yourself to look at when your drawing what ever the subject is.

of course, I'm not a professional artist, and I haven't much experience on drawing compared to others, I'm mostly stating things I personally find helpful for me that I think might help others.
