Mario and Luigi SS style sprites

[The Phoenix of Life]

Well, this actually isn't my first shot at spriting, believe me. I started with absolutely terrible recolors before I actually knew what spriting was, but I've come quite a ways since then. Really, I was only nervous about being criticized, not worried about that now, though. But anyways, thanks for the advice. I could work on fixing the pillow shading later, and might I ask what AA means? I'm not exactly familiar with the term.
