The proportions are really weird, she looks like a midget.
Just look at it her head is as wide as her body.
and if you didn't know a normal human's head fits 7 times in his/her own body.
your sakura's head fits 4,5 times in her body.
The hands and arms are to thin and small as well, same goes for the legs.
fix the proportions.
I dont know what refs you used for the body but they must have been messed up :\
