Oh cool. I used to have the same type of goal. In fact I used to draw myself, but I have yet to actually make anything of it.
My previous drawings that I'm somewhat proud of still (all anime though...):

Meh.
EDIT: I haven't drawn in years btw. The last ones (Naruto) was back in my... junior year of high school I think. Which was 2006-07. It was a free drawing assignment and I got an A on it. Aww yeah.
Oh and the rest (the YYH ones) were from like 7th/8th grade.
God I wish I could improve.
