As someone else pointed out a while back, Mai doesn't have gold eyes. If you draw her again, please try to remember that they're gray (brown in some light sources). Other than that, this is pretty much flawless -- you've captured the character while allowing your own style to shine through.
This is amazing! For a second, I thought it was lineart from the show. Everything's great - her expression, clothing, hair, and the perspective are really, really well done. The only problem here is Mai doesn't have golden eyes. (They're a dull brown.)
