Ehh AA has nothing to do with pixel overs xD AA is the way to 'clean' a line, and make it fit better into the background.  Anyways, here is some crit ^^

It sort of looks like you're using the line tool insed of the pencil (Not acusing you of anything), as you have many straight lines that would look better curved, like the left arm (our right). You also need some contrast in your shading, as the current shading is barely noticable. As a final suggestion, try and darken your lineart in some places ^^
