Step 6: You’re done with the initial sketch! You have the basic Princess Bubblegum shape, so now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 7: Princess Bubblegum has tiny eyes. Draw them as dots sitting on top of the horizontal construction line and on either side of the vertical construction line. Right below the horizontal construction line, draw her mouth, which is a curved shape similar to a sausage.
Step 8: Inside Princess Bubblegum's mouth on the top part, draw a line to represent her teeth and on the bottom draw a curved line for her tongue. Draw the side of her face and neck using the original circle and neck line as guides.
Step 9: Princess Bubblegum's hair is tricky, so it’s divided into two parts. Start by drawing a line above her eyes across her forehead to create her bangs. Then draw the line down toward her body and create two bumps at the bottom similar to an upside-down heart. Keep drawing the line upward until you reach the to of the body.
Step 10: Draw the left arm using the initial line as a guide. Draw Princess Bubblegum's sleeve as a half circle hiding behind her hair, then add two bumps for the frills. Thicken up the guide line to create her arm and then draw her hand using a series of curved lines to form her fingers.
