If you want to make him look intimidating in a less cartoony way, here are some thoughts.
I am not a wolf expert, but I think they snarl and growl to intimidate, and bark while attacking and chasing. Here's an snarling head edit:

His main method of attack seems to be the fork he is holding, so the most intimidating thing he can do is pose himself ready to use it. His right hand seems to be unused; in battle, this is a hand wasted! If he doesn't have a shield to hold, why not hold his weapon with both hands for better control and more power?


If you imagine this man holding a fork instead of a sword, and with his hands spaced further apart, then this stance is similar to what I am imagining. If you combine a threatening stance like this with a head thrust forward in a snarl, I think it could look very intimidating.
Here is a video describing spear stances and striking methods, which might be applied to any polearm, like a fork. You might find the "pool cue" striking method interesting if you are going to animate an attack.
