First Lesson Drawing Tutorial ... see Julia's version!

Hey Students!  I can't believe I just stumbled across this. Take a look. It's so nice to see a sphere drawing tutorial on-line that mentions both the importance of the terminator along with the graduation of the half tone on the lit side of the object. If you've taken my drawing class and this looks familiar ... bravo!

Take a look. Thanks to Julia for posting and for taking the time to create the corresponding images!!
