This is funny, because I do all of my one-frame sprites so that they can double as portraits and small pics.
I've done some art for the contest entry I'm working on that is absolutely diabolical.
After the design is out, I will do versions of the portraits in the regular size for 1024x768 to put on my web site.
Actually, it looks like I have several new portraits that will be making their debut in my contest entry.
