A friend of mine, Nyx, has recently taken up the hobby of making pixel dolls as one way of practicing her art--and building her own game world.
She wanted some practice, and I was only too happy to offer to "let" her make one for me. The Bookwyrme below is based on my primary gaia avi.
Nyx is also the one who made the funny little dragon I use on some forums.
Take a look at some of her other work on her deviant art site. I like the Old Mother myself. In fact, I tried to get her to let me use it for the mod I was talking about earlier, but she says someone else has already claimed it.
