Pretty rad. The composition and coloring is very nice. But it is a shame that all of the detail on the viking is covered by the shadow. It makes him look much more threatening and makes his hand and his goblet stand out. The green smoke from the goblet looks a bit meh, may have been better to do some green highlights around the upper body and/or used just the gradient clouds. Aside from that he and the background are detailed well.
Horns are to cool not to have on vikings anyways.
