Here I include some of my comments to your demos:

×1S: Yep, looks right. You made it somewhat fiddly, the west alcove can make putting the mirror into place much simpler.
1W: All good.
1N1W: Also looks good.
1N: All three passes are as they should be.
Entrance: Yes, good.
1E: Ech, you slightly broke this one.
1N1E: Your solution to the entry part is different from mine, but amounts to roughly the same result, I think. I'll leave it as is.
I sent you a message with the tweak request regarding 1E.
Otherwise, I'm happy with my entry.
