alrighty, this is for bacon (or anyone that can make sense of it really) since i told him i would sketch up some examples of skeleton outlines and whatnot for him - when i tried to scan 'em in today i came to the wonderful realization that my printer had quietly decided to stop working as well :/
when you're doing faces, generally you're going to start with a basic shape - circle, oval, square, pretty much anything depending on how cartoony it is going to be. you'll want to draw a line going straight up and down and curving up at the top to show where your features are going to be. if the line is in the middle, the view will be straight-on, if it's on the side, it's going to be a profile shot, etc.
you do this to help keep your facial features where they need to be as you draw the face. when you don't do it, all kinds of things can happen. it can end up skewed, bodyparts can be on entirely wrong angles of the face, eyes can go drifting off into nowhere, etc.
here's a musculature that ven did of my dude to help me correct his weird anatomy. you probably won't want to worry about going that indepth with muscles and the like until you're a little more comfortable with basic outlining and anatomy in general, but you can see the basic shapes & lines under there
i hope this helps :/ i'm super tired and probably incoherent right now
