One of the facial expressions an artist may need to draw is a tongue extending from a mouth. This is not a difficult image to create. The tongue can be drawn using a basic shape. The key to drawing the tongue extending from the mouth is to use appropriate shading and the ability to draw the features of the mouth around the tongue, allowing you to keep the central focus on the tongue itself.
Draw the tongue first. It will be the central element in the drawing and will limit the portion of the mouth you need to include. Begin the tongue with a vertical line and a very slight curve to indicate the tongue extending from the mouth. Extend this line toward the bottom of your paper, narrowing it as you reach the point where you want the tongue to end.
Curve the line for the tongue around to form the tip of the tongue and extend the line toward the top of your paper, ending it where you began the first line. The space between these two lines is the tongue and will vary depending upon how wide you want the tongue to be. Curve the tongue line slightly upward if you want the tip of the tongue to be curled up.
Draw the lips around the tongue, beginning the lines on each side of the tongue just above the tongue lines and extending the lines to form a mouth around the tongue. Only the portion of the lips not covered by the tongue will be visible.
Draw small squares above the tongue for the upper teeth. Shade the tongue fully using angled strokes to colour and texture the tongue. Leave the teeth white or shade them lighter than the tongue. Add dark shading to the space between the tongue and upper lip to indicate the interior of the mouth.
