The last couple of drawings you've done have used a lot of black. Makes me think of comic book style shading. Shading with black can look really bad but you have used it really effectively here. Good job.
I really feel there's something different about the colouring here, the shadows are like, hmmm, I can't place my finger on it. It's not bad at all, but it's something different idk. He's like "It's not like the snow's cold or anything, b-baka"
the shadows are a lot darker than usual, the overall picture is a lot darker than it would normally be. I started with the shadows and built up the light rather than the opposite, which is what I would usually do.
