It looks wonderful, like everything you did.
However, as someone who plays on an old computer, I don't look forward to additional transitions. Especially here as BG is also a quest hub.
(A transition takes 30~90 sec. for me.)
For ease of play, I would suggest placing any merchant/quest giver outside of his building. (No need to go inside, so the building could be a static one.)
I cannot see how a new BG would improve any RP activity there, as with four sectors it would be even more empty overall.
A lore accurate layout is nice to have, but if it doesn't have any actual in-game function - what does it really provide for the overall player to have it as exactly as in the sourcebook?
For example additional taverns - these would be as empty as the ones we have already.
Or more temples for all the deities that were added recently? If anything players should RP worshipping these gods and if enough band together they could build/fund such a temple.
Wouldn't a reduced (in size) layout provide a better chance to meet someone?
Is it easy to transfer all the existing quests to the new layout or would that open up a new can of worms (as buggy as changing a quest was in the past)?
The Wide could be wider as more merchants might appear.....
Please get rid of any overhead tent (like in the wide currently). It is difficult to walk/interact under it.
I have to stay zoomed in fairly close to make it work, which isn't how I generally play.
