This is nice, very cool concept. I love the pose Sub-Zero is in, its perfect. I suppose the costume design is fitting, since this isn't the current Sub-Zero, a plain 'ninja' outfit is fitting I think. The only this is that is eyes don't appear to be looking 'up' at Hanzo's head. Maybe its just me though.
Good details on the spinal column, thats amazing. The bloodwork looks exceptional, can't wait for the colorization on that. Good work with Hanzo's head as well, he does look 'dead'. But the head seems a tad too small to me. Anyway, great addition by adding Scorpion in the left hand side of this. The flames look very well done, and there are alot of nice details to the skull. Overall, I like this alot, nice.
I like subzeros body and pose very much- the anatomy and design, although simple (and uncluttered, which I like), just looks perfect. Great work........ ps- I think you could make a living at comic/action style character illustration.
