Oh, also, another way to antialias the hair there would be like this:

You can do this if you don't want to break up the line, but take note that it makes the line look thicker. Anyway, best of luck!

 You've got some nice outlines going there, but one of the first things anyone will tell you is to antialias some of the jagged lines, like here:

Also, those toes could benefit from antialiasing, since you've got some banding going on around there (if you don't know these terms, there's a nice tutorial on the forums with your name on it, so to speak!) Overall, though, quite a nice-looking start you have.
