Yea I used to spend hours playing Final Fantasy Tactics. At first you have to be the boring, lowly squire, who can't really do anything cool, before you level up and can be a knight, or a black mage, or something cool.
So yea, right now I am just a low level art squire, haha.
If I had the opportunity to choose the way my life was going to go, I would like to be a really good illustrator. Someone like James Gurney has amazing ability with everything you mentioned: anatomy, color harmony, composition. So I am going to focus and get good at everything!
I think right now my anatomy is passable. Maybe like a 7/10 (too generous? :P)
...but I know next to nothing about color harmony and composition. I was reading an art thread the other day and someone recommended the book Color by Betty Edwards. Maybe I will start there.
