I've been a beginner for years. Drawing mostly 3/4 view faces in the bottom of a page and not learning much (or even trying to).
Only very recently I decided that I wanted to take drawing more seriously and try to put in a good few hours every week. These are some of my sketches from late 2012 up until now. Lately I'm trying to spend most of my time drawing hands because they are the most daunting and difficult.
The first pic is copying Eduardo Risso from the comic 100 Bullets. The bottom 3 pics are from this week.
