All you have to do for your last drawing step is draw out the shape of Itachi's legs and then draw his shoes, and feet. Be sure to include the toes, as well as the detailing around the ankles as shown here. Next and lastly, you can now sketch out the rest of his hair style, and then his ear, eyes, nose, and mouth. Once completed you can start erasing all the guidelines and shapes that you drew in step one.
