You're getting better and better...but you have massive spacing issues with your new secondary battery. Spread them out, and you can just put them straight onto the deck without any need for an extra deck level. Your ship is big enough. Then, make better supports for the mast. The poles are to thin, and that support you have directly under the spotting top won't provide much support. Try making it a diagonal support instead of the L-shaped ones that you have right now. Then, make a bigger platform for the spotlights, and add some sort of ladder to them. The one you have right now is very overstated compared to what is looks like in real life. Finally, make the amidships cranes bigger, or make those boats smaller.
And just as a last touch, try redoing the bow. Its not within the same time period as the props or the weapons that you put on the ship. And get rid of that glass viewing deck on the stern. It would do the ship no good in stormy weather.
Are you talking about the 6'' guns or the 4.5''?
