Mind if I inspire one more idea?
Have him raise both arms with sword and shield at hand and throw both objects down with an impact. It should be like a Passive ability, akin to critical strike. I really like your model, BTW, and I encourage you to make him increasingly badass!!
Attack Defend can have more of a kick to it, but i like this quite a bit, i would use Powerful to describe this model. it gives that feeling off.
not a bad concept for any version either which is what i like about it.
Can see a Death Knight with this theme, or human, troll.
