How To Draw A Mouth
This film will teach you how to sketch a mouth. This is a typical pencil drawing exercise for beginners, to help you practise the positioning and proportions of a mouth within a face.
Step 1: Positioning of mouth
To get the mouth in the right position on the face, start by drawing a face roughly in the shape of an upside-down egg, and then draw guidelines to divide the face into three sections. Draw the guidelines so they're curved to the bottom, and draw them faintly so they can be erased later. The top two sections should be roughly equal in size. The bottom section should be about half the size of the other two. Draw another guideline vertically down the middle of the face.Step 2: Drawing the mouth
The bottom curved guideline represents the parting between the two lips. Just above this line, draw a small upward curve that will represent the middle of the top lip. Draw two dots on the guideline which will represent the outer tips of the mouth. For an average-sized mouth make it roughly a third of the width of the bottom part of the face. Draw two gentle upward curves to represent the top edge of the mouth. Then draw along the guideline to represent the parting between the lips. Start drawing the bottom edge of the bottom lip, remembering that the bottom lip is usually thicker than the top lip. Don't draw the edge of the bottom lip all the way to the tip of the mouth. There isn't usually a hard, defined line between the outer edge of the bottom lip and the surrounding skin, so you'll use shading to blend them into each other. Now start shading the lips, remembering that the top lip is usually darker than the bottom one. Use an eraser to gently soften the shading. At this stage you can also erase the guidelines in the drawing. More shading around the mouth will help set it within the context of the face.cited from : http://www.videojug.com/film/how-to-draw-a-mouth
