In this tutorial, we learn how to draw a sphere in 3D. First, draw a circle and a square around it with a light pencil. From here, you will use the side of the pencil to shade in the sides of the circle. Then, draw a half circle next to the circle to make it look like it's shadow. Shade that in and then add in more dark markings to the circle, leaving a small white area on the top of it. After this, draw in the outline of the circle and erase any stray lines. This will complete your sphere, enjoy!
