Cute!!!
Based on what you have, its good! The clothes are a bit difficult to shade and i think you did well.
it helps me to think about WHERE the livjt comes from, left right up down behind, ao it doesnt look like the light is all over the ppace
it can also be helpful to color the wntire piece in a multiply layer of your shading color and then erase where the light us instead of drawing on the shadinfo
