What is in the image: his image is a tutorial on drawing snarling and smiling expressions in canines. it uses sketches of wolflike faces to illustrate the three main muscle groups involved: the levator (for the "snarl"), the zygomaticus (for the "smile"), and the buccinator (which affects the overall shape and tension of the mouth). the sketches show how these muscles work together to create different expressions, emphasizing that the nose doesn't stay in one position but moves along the curve of the jaw when the animal snarls. the tutorial also points out that frowning is a cartoonish expression and not a realistic anatomical one. various annotations explain the muscle actions and their effects on the overall facial expression.
