Dreadnaught Class Heavy Cruiser

The vanilla image: http://img.swcombine.com/ships/6/large.jpg My character in game is a privateer with a letter of marque from the Galactic Empire. I'm looking for a custom that will fit that sort of character without being cheesy. I'd like to avoid having the Empire logo anywhere on the ship as I am still, at the end of the day, a privateer. Any help would be greatly appreciated.
