Ever seen something like this?

Eye candy! Begins to look more like the ST canon ships' interiors...

Nice stuff. Would be cool if they would add more decks or balance the decks in accordance to the class ship you choose. Not suggesting 24 decks as some Cruisers have, but a few more with good functionality would be spot on. Currently we can use rommy ships lounge for fleet meetings as they are big enough, but the one's on the feds are pathetic.

You can use the size of your ship interior from the ship designer or however the one vendor is called where you can paint your hull...
A FED ship can be huge but just a few rooms with interaction possibilities
