For starters, this is an awesome pic. The girl is cute and I like your multiple layers of shading. The pose is great too. I'm not quite sure what she's sitting on though. Is it a green wall? To be nitpicky, I think her kimono is too short for winter. =P Also, are mittens usually three-fingered? The ones I've seen have space for a thumb and the four other fingers. I'm being picky again, though. =) Great job all around. Keep up the great work!
