Step 1: Draw the three shapes that you see and notice their relationship with one another. The headband shape is about 1 and 1/2 times the height of the top of the head. Melo's hairline forms another shape between the other two and starts close to the half way point from left to right.
Step 2: Observe, then draw in the ear and the two eye shapes. Notice that the ear fits perfectly in to the indentation of the headband. Notice that Melo's right eye shape starts at the same point as the hairline shape above it. His left eye shape is heart shaped because of the angle of his head. Finally, notice the triangular shape in between the two eye shapes and the downward angle that the eyebrows point.
Step 3: Add the nose shape and the shape for the cheek.
Step 4: Add the smile line. the moustache and the upper lip. Notice that the smile line goes slightly past the edge of the eye shape from step 2. The moustache and the lip are about the same width.

Step 5: Here is the trickiest step. I added 5 rows of shapes in this step. The top row is the gum line. Notice that there are seven points to the gum line. The next row is the teeth. There are eight teeth visible and due to the turn of his head, each tooth gets bigger from left to right until we reach the last tooth. The next row is a narrow dark space under the teeth. The row below the dark space is slightly thicker than the previous row, but not as dark. Leave the bottom row unshaded for now.
