>>3666258Glie is wonderful, it's atmosphere contributes a lot to the show. You've probably seen it already, but I found this map a fan made on Twitter.
https://files.catbox.moe/69wkxv.jpgAs for your final request, I'd only do that if I found an artist I'd trust not to upload it anywhere. I haven't done it for fear of that very thing happening. For my next commission I have an idea that's a bit embarrassing, but spoilers don't work on /c/ so I'll have to bite the bullet: a wedding dress image.
Also, I think Haibane Renmei really does get better with each rewatch, there's so much little nuance in every scene, even the "mundane" ones. I just realized that Rakka saying that she can't stay in the guest room forever and Kana talking about not feeding the crows lest they get too comfortable are both allusions to the purgatorial nature of Glie.
I'm a very slow person admittedly.
