As for your specific attack, to be honest the only real problem is that you've gone for two moves in one post, but also that you had your minions get dressed first. Skallagrim probably wouldn't wait around for that. Raising your hands to shoot a fireball is slightly obvious, but also unavoidable, and coupled with your distracting elements it could be useful, especially if you had them attack from blind spots or some such, though I suppose that might be beyond your character's control.
