Step 25: Darken the shape under the leg on the left to create Bart Simpson's first shoe. Draw a line at the bottom for the shoe's sole and a circle as a design element.
Step 26: Draw the shape of the leg on the right around the initial guide line. Add Bart's sock at the bottom using a couple of curved lines.
Step 27: Darken the shape at the bottom for Bart Simpson's other shoe. Add the line at the bottom and circle on the side.
Step 28: Darken the shape under the feet to create the deck of Bart Simpson's skateboard. Add a long horizontal line at the bottom of the shape to give the deck some thickness. Draw a couple of lines on top of the deck as a design element. Don't overlap the shoes. You can stop here if you want Bart to be riding a hover board!
Step 29: Draw a small circle under the board below the left foot for the first wheel. Add a smaller circle inside for the axel nut and a line on the left to give the wheel thickness. To the left of the wheel, add a couple more curved lines for the visible part of the truck. Add the visible part of the front wheel on the other side using more short, curved lines. Draw a small circle near the back of the board for the other wheel. Use a series of curved lines to make the wheel thicker and to add the wheel on the other side.
