I am finding that I am drawing kids with the same boring head shapes. So now I am trying to improve my concentration on the DIFFERENCE of each particular person. Why is this person different than somebody else? I read somewhere that " . . .Anytime you're doing a strong drawing of anything well, you're depicting it is DIFFERENT from something else." (Milt Kahl)
So from now on, I'm going to be thinking a little bit more about a character before I just jump into it. Also I found a really great quote about drawing from life by Art Babbitt:
"If you can't draw,-forget it. You're an actor without arms and legs"
