Wonderful work David. I`m always in awe of the intensity of color you achieve with a very muted pallet.
The Axe works especially well, almost looks like NMM with acrylics ?
If I may, I think while your wanting a "cold" piece, that white skull tends, IMHO, to merge a bit too much with the snow/ice and a brownish age stain might help that ?
