As you know if you read Why I'm Learning to Draw, I've scarcely drawn anything before this year. I was more interested in math and music and books and history and all sorts of other time-consuming things.
Now that I've started drawing, I have a very specific interest: drawing faces in pencil. To improve my skills in this area, I'm just going to draw lots and lots of faces, and when I think it will help, I'll research books and websites that address areas that I want to work on specifically.
Each post is of a face I drew, scanned from my sketchbook. (If it's a person who is known to me personally and is not a public figure, I'll Gimpshop out their name unless they give me permission otherwise, as noted in the Privacy section.) Under the scan are various comments about the drawing—what I think I did well, what I know I need to work on, what was interesting about drawing this particular person, etc.
Each post has a couple of tags: one describes the person (baby, child, woman, man), and one describes how I know them (for people I know personally: family, church, school; for people I don't: tv show, movie, etc.). This way, for example, if someone I know from church happens across the blog and only wants to look at pictures of people they know, they can click on that tag instead of wading past a bunch of people they've never met.
