Advice for a beginner?

[getmeoffthishellsite]

For Christmas I got a pen tablet and I'd like to start drawing peoples' avatars.
Does anyone with experience have any tricks or tips for a newbie in the trade? (Well, besides practicing. I still need to do more of that...)
It would be greatly appreciated
