Step 5: Now add the bottom portion of Marshmello's eyes by drawing two big w-shaped lines. Use the construction lines as guides to help you determine how low to place these lines.
Step 6: Draw a long, curved, horizontal line for the top part of this Fortnite character's mouth in the area between the eyes and the bottom of the square. Pay attention to how Marshmello's mouth slopes to the right to follow the lower edge of the initial square.
Step 7: Add a second curved line at the bottom for the rest of Marshmello's mouth. This line should almost touch the lower edge of the initial square.
Step 8: Darken the top and bottom of the initial square but make the lines curvier. Follow the slopes of the guides to make Marshmello's head tilt.
Step 9: Darken the lines on the sides to finish the shape of Marshmello's head. At the top, draw another curved line for the front of this Fortnite character's head.
