Wolf Sculpt

Hey! Long time no see!

So I'm working on my Halloween costume for this year and I'm trying something new. I'm doing a sculpt of a wolf mask that I plan on casting and using in a faux wolf pelt headdress. It's going to be a direwolf/werewolf, but I want it to be as realistic as I can get it. This is the first time I've sculpted a realistic head, but I'm kinda surprised how stumped I am working on this!
I plan on ordering a DVC nose and eyes (the ones you'll see in the pics are just place holders), but I wanted to get the rough shape and size of the rest of the face first because I have NO IDEA what size to order. Actually, if you can suggest a size nose/eyes for a realistic-style werewolf or direwolf, that'd be great too!

Anyway. I'm not sure if I'm doing this right. Let me know if you see any problems- symmetry, size or otherwise- happening yet. Redlines also great!
