I would like to suggest some things though. I suggest doing your own japanese posters or find other posters that actually translates something related to your showcase, otherwise, things might go wrong as for some japanese posters are not actually related to your showcase.
And I also have a question, in this alley. How do you put an end to this alley? A forcefield block, or a black wall? I’m curious!
This is beautiful, you inspired me to make something similar. You should make a game showcasing it. The level of detail is astonishing, and the style is incredibly aesthetic.
Keep up the awesome work!
EDIT: An amazing map like this could be a lobby for a game. It looks like a place where an amazing story happens!
