This is wonderful! I like your shading and colouring techniques. Try doing hair in actual strands, detail looks lovely in any art piece. Anatomy could use some work; to me the breasts seem rather large for her body
I must say that this describes near correct anatomy as in anime/manga. and moreover it has that characteristic reddening of the cheeks when something awkward has happened ( which is almost all the time in anime). A skillful approach, this shows much potential ... take care..
