Yes, very nice built. The vessel with its outriggers seems rather like a Hemiola than a Bireme, so I would say it will work as a 4.- 1. cent. BC Ship.
It looks great but if you want to have a historic accurate model you shouldn't fix a tower or assault bridges with such small ships. Another problem are the rowmen, with a flat close deck the would choke....I know an open deck, the problem with the rowers figures and so on - i've the same problem...
