Firstly let me say that I know absolutely nothing
about making maps yet.
But in my user-only opinion, this is looking sweet
said, a curve would be nice for the upstairs wall. Also the bot-routing seems a little strange, but I assume that would be the last thing to be polished on a map (like I said, I don't know!).
But yeah, very impressive so far!
Now if only I could find a Final Flight of the Osiris Dojo...
Keep up the good work!
