Actually, Dunwall is supposed to be based on England. (but I like your design anyway)
Yes, I was reading the wikia and other infos over again. Dunwall (Gristol) is based on England, France, Germany (?) and I happen to have a couple ref photos of France close by so I just went ahead to use that.
I do want to get my hands on their art book though, hopefully get an idea of what draper wards’s concept design actually looks like
