The best bit of advice I could give you in learning it is to go slowly up the levels, its so so tempting to just divide a few times then sculpt in the high levels but move up and gain form at each level.
Do a lot of little sculpt strokes with a low Z intensity, pull/push it a bit more than you need then smooth it back to fit, you can gain a lot of the overall form using the move brush and then onto the std brushes to refine.
I found it hard to get details such as pores, and wrinkles in there when I started, hell I still do on a human model, a fantasy one it dosent really matter and its a good place to mess about with alphas etc.
Just my workflow
