i have been drawing for about as long as i could hold a crayon, but i didn't really start drawing until about middle school. so about 2005 would be about when i started to really study anatomy. i have only been doing digital art for 3 or so years and i started with "paint" that anyone can find on their computer.
if your just starting out or don't have the confidence to keep trying just remember two things,
1. it doesn't matter if your good or bad, you are better then you where before by just trying.
2. to draw is to see.
