This Republic Frigate by yoshix was his attempt at making a closer to minfig scale version of the prequel era cruiser. I'd say he managed to do a pretty good job at that and the overall look is pretty slick. He says it's not quite 100% where he wants it to be, but it's close and if you plan on going to Brickfair you can catch a glimpse in person.
You can check out more detail shots on MOC Pages.
