Thanks.
I'm very happy with it. The secret is understanding anatomy. You have to understand all the proportions, bones and muscles of the human body. This is what I've been doing recently. I can now tell when people do not understand this. The key is understanding where muscles connect to bones and hence what those muscles actually do. You can then draw characters from your head that look like you drew them from reference material. For example if I wanted to draw someone smiling, I now know exactly what muscles do this movement. I come from a traditional art background which obviously helps a lot but the anatomy knowledge is new.
