Awesome piece, love the threathening mood and the sense of movement! I like how you used so much contrast, especially with the teeth. They really stand out and I guess that's what you would notice first if this thing jumped out at you! Terrifying but great
The perspective is awesome and makes it all the more terrifying. The strong contrast between the dark silhouette and the bright white teeth works really well. And it's nice to see snarly werewolves for a change instead of friendly ones.
The colour scheme is simple, but the perspective and foreshortening is brilliant - these are two of the hardest things to pull off in figure drawing, and you've done it masterfully. The blurry background is a plus - there's a real sense of movement here.
I imagine this is the last thing that many a dreamcatcher-maker sees...
