Where Do I start?

Frequently asked question... And I don't blame you, I asked the same thing.  (Not saying I'm an expert or anything).  I started with the head and then worked my way down the body.  Usually people go straight into the facial features when starting.  That's probably the best thing to do.  BUTT (lol butt :D. ok. back into seriuos mode -.-) You should start with one thing and somewhat master it before moving on.  Most importantly keep trying and practicing and you should be fine ^___^.
