Here we have a Musketeer Officer. He has a sword and a pistol. He gives the orders to charge or fire the cannons. The Cannon guy also has a pistol and could be used as a soldure who is just carrying a torch for light.

I'm not too sure about how the pistol turned out. I thought about making it bigger to give it more detail but I thought it would obscure too much of the character.
