I'm having the same problem. It's pretty hard to start, but even when you start and things start to shape up a bit I get a bit lost.
I also get lost when I see a very good finished drawing. I actually get discouraged.
Now I know drawing is hard but at the same time is easy. YOu just have to start from the begining and work your way up. I'm talking here about the drawing process.
So, any help on this?
How do you people start? What is the first thing you do? After you have your shapes, (or whatevar you have) what do you do?
