Oh yeah,
It was hard to tell cause there wasn't anythig else to compare Yamato to except another Yamato in the distance. LOl put a plane on the deck or better yet on top of one of the turrents an do a top down shot wit the bow and stern just within the edges!
I did that with a Veritech on the Xanthus class carrier and you can only see it on a (small) cross-section that fills the screen.
As for the Andromeda, though it's a wire-frame and not filled yet I say you got it right on! [Sweet!]
I am not familiar with the other one but seen pics of it, Looks accurate also. Is that also 2km?
More importantly, are you planning on making them available?
(oooo I'd LOVE to experiment with the dual main guns!)
I have to ask.. Do you have a pic of the Wave motion gun in action?
