Following the image guidance, draw basic circle and line shapes to create the outline of Stitch.
Sketch in guidelines for the face. Position the lines where the eyes and mouth will go, plus a central line down the face.
Sketch in his claws as well.
Draw half or full ovals for the eyes. Draw a large circle for the nose. Add some scars for Stitch, who has some “chipped” or scarred portions on his ear. Draw in the mouth line, along with teeth. Add in the little tuft of fur sticking up at the top of Stitch’s head. Sketch in color separations as well.
