Again, cosplay. Tell me your favourite comic, game, or show cowl, I'll show you what it looks like in live action. For me the must haves are wider mouth hole. Preferably with little points by the cheeks, a bump where the ears should be, sculped angry brow, small eye holes, and preferably longer ears. Short ears are ok, but not the tint little nubs they give him now. Looks like Catwoman. Leather preferable to armor.
