Haha, thanks! Well, I'm going to guesstimate that it took about 20 or so minutes like Hunter said, since it was during class and I worked on it in-between taking notes. It's not that big of a picture since it was doodled on the corner of printer paper. ^^
I'm not really sure when I really started drawing. I have sketchbooks from preschool; however, I believe I started to actually expand in my skill after I graduated high school. Although, I would really like to get better at digital art, but I keep going back to graphite and paper. ^^;
