*Stares absentmindedly at the drawing*... ahah, seems like her expression is just somehow contagious ^_^'.
Really nice tones of color, shading is great. Maybe the falling leaves are a bit too 'blue', it makes them stand out too much (compared to the mostly green tone of the drawing), but that might be because it's the center of focus for the girl.
Anyway, thumbs up and fav, really relaxing work ;)
