Wow, I'm really impressed! I'd about given up on this ship ever seeing the light of day, but it's looking almost ready for textures! I agree that it looks like it managed to keep just about the right amount if recognition while making a fresh take on the model, taking into consideration all the feedback and guidance (and debate) that's been thrown into it. Job very well done, and I look forward to seeing it to its completion.
As for the folding up wings, I think a good 70 degrees would work quite well and prevent the middle wings from having to fold as well - they could remain fixed with the vertical stabilizer, adding rigidity and cutting down on complexity. Keep it up.
