Interestingly I rather considered it a bit too muscular already, when compared to http://www.uesp.net/wiki/File:BM-creature-werewolf.jpg. After all, werewolves are supposed to be the ultimate hunters, and hunting isn't all about muscle. It needs speed and stealth, in addition to being able to hit hard, and muscle is very heavy.
Heaving options is always good, though.. that's what modding's all about. I'd be curious about what alternative werewolf models there are. The only two I'm aware of are La Femme Lycana (a female-specific werewolf model) and Tales of Lycanthropy's alternate model inspired by The Howling movie.
