Trying to conquer ZBrush

So with the precious time off I have between semesters I have been trying to figure out ZBrush. It has been called the photoshop of the 3d world...Its really cool, If I can just figure out the basics. So far Ive learned how to make normal maps and how to cross pollinate with 3ds Max and learned the tools..Thats about it. Heres a sample of my fooling around in Zbrush with a model of mine from 3ds max.
