Below is an image from George Bridgman whose book, in my opinion, is a great starting point for cartooning students who want to kick it up a notch.
Bridgman, in his anatomical schematics, exaggerates in order to help you feel the figure's contours and they are not to be taken as literal document. People don't look like Bridgman's figures but Bridgman's figures look alive.
We also discussed clothing folds. Accuracy in dropping in the lines representing the folds in a character's attire is important in making the action in an overall comic panel feel right.
