Firestar,
I wish you all the best for this huge and interesting project.
Modeling and bringing such a large ship in a simulator or game is really a true big challenge if you want to make it really accurate and capture the essence and realism of the real ship.
I keep an eye on this project and I hope he final result will be appealing and convincing enough. I can see you've already worked a lot on it. On top of the obviously needed ability, long and difficult projects need hard work, motivation, search, time and tenacity.
You have all my encouragements for this one.
