Oh wow, that is really great looking. I'll update the first post with the model.
Hmm... as for input, let me think. The only ideas I have at the moment for revisions to the model would be in the bow area. Perhaps making the engines that hand down below the command decks angle out away from the hull slightly...like how the engines on the Percheron. Also I think the command deck should be more wedge shaped, rather than block shaped...I have the Shire's front end in mind.
But she is looking beautiful sir, I never would have pictured that one of my designs would be modeled.
