Good work!
I thought smile was "weixiao" I see xiao, but the other two I can't read :/
But that aside...
I think the face is the best part of this picture. It's definitely proportionate and for the most part anatomically correct for your purpose. Although I don't understand how the hair got behind the eyes....
As for the rest of the body, I think you mostly need to work on symmetry. Either arm looks okay, but when you put the two unlike limbs together, it looks a bit weird. Same goes for the legs.
P.S. you should have drawn a smile on her face haha
