Absolutely a beautiful rendering. Hands down. I would love to see her in my fleet.
Can you take a small little nitpick from an old geeser?
Let's pretend this is real life. As beautiful as she is... a few well placed photon shots (ok more than a few) and in theory you could blow the secondary hull/engineering off, including the nacelles, crippling her. (that is if of course this was real)
Would you consider, if it looks good to you, adding a 3rd nacelle to the main hull. It could also open up the possibility of having a ship that could separate into 2 ships, similar to the prometheus. Just a thought.
In any case, very well done and truly you are a master at your work. I look forward to seeing her finished.
