Hard to review
I dunno where to start, it's a very wild and dynamic picture. The face looks a little slapped on, but then again it suits the way you drew the knife and the wavey abnormal arm on the left of the pic.
I love the monochrome style and the different blues give a really cold feel. I also love the storming snow, the background and the snow ground, good job on all of that.
I looked at this pic quite some time now and also many times when I tried to start a review before and I feel like I'm "not done" watching it yet. That may sound weird, but I think that's a good sign.
I personally like the picture and the style you used a lot, so my 10/10 and 5/5 are probably not very objective.
