Yeah, something i should've done a couple years ago.
I'm doing these as a "how to draw Simpsons guide" for a friend (a damn good "apprentice", to say the truth

), but i found that they are helping me a lot too. I have to re-learn to draw Simpsons, since it's been so much time since i did a proper drawing, and since forcing myself to complex pics right away just frustrates me with no results whatsoever, i took this occasion to just start from scratch: what i learnt to draw first was Lisa's head... and from there i shall start again.
A couple of comments from other people convinced me that this might be helpful for other visitors around this board, so i'm going to post in this thread whatever kind of tutorial comes to my mind as i go on. Hoping it will help you as much as it helps me.

I know that just looking at the pics won't explain properly about details such as sizes or tricks, and i am aware of the fact that my method for drawing is not quick and easy at all. Many of you might want to draw in another way you feel more confortable with, and it might come out better and quicker. It depends on the person really, and i don't want to seem like i possess "the truth" on how to draw.
But if you're interested, fell free to ask here and i'll try to answer as clearly as i can.
So, on to number 1:
Lisa's head
