Well first of all, the shield in real life wouldn't stay in one direction, it would tilt around. Its exceptional for a first gani, but if the shield hits someone's head, at least add a sound to make it actually look and sound like a shield is hitting someone on the head. Also, it seems like people wouldn't throw stuff to the left with both hands, and to make the arms facing the left and they are throwing to the left. Last, make the arms with a body, or else it looks like random arms throwing a shield.
