Step 15: Draw the shape of Oogie Boogie's first leg and foot around the guide on the lower, left side. The top of the leg should be wide, and the foot should be thin and short.
Step 16: Draw the shape of Oogie Boogie's other leg around the guide line on the right the same way. Make this leg similar to the other one. Sketch lightly at first and only darken the lines when you get the shape right.
Step 17: Go over the final sketch lines of your Oogie Boogie with a pen, marker or any other type of permanent ink. Take your time and be careful when you ink to avoid any accidents. After the ink dries, get rid of every pencil mark with an eraser for a cleaner drawing. Fill in the shapes of the eyes and mouth using ink as well.
Final Step: Color your Nightmare Before Christmas character using colored pencils, markers or crayons! Use yellow-green for Oogie Boogie's entire body. Color lightly at first and slowly build up to the intensity of green that you like. This is Oogie Boogie's look under black light. You can also color him light brown for his more natural look. Add a bit of dark green for shadows. Don't forget to pause the video to draw at your own pace.
