Finished off most of the hull detailing on the back half of the main fuselage:
And, at long last, WINDOWS!
Note that not all of the windows have been modeled yet.
Something else worth noting is that I froze and optimized a number sub-D objects, which reduced the overall poly count by more than 25,000, even with the addition of the windows and other hull details. Current count stands at a little over 441,000 and my goal is to keep the end result under 500,000.
