Your ships look great.
I have friends who do WW-II navel battles in 1/700 scale.
Your ships would fit right in with the plastic ships at a very economical cost.
A plastic 1/700 Tamiya Yamato Battleship costs about $23 - $40 and kits with photo etch details will cost $70 - $100.
Obviously, the cost of a fleet of 1/700 scale ships is a major investment.
Paper is much easier on the pocketbook.
