Phil brought up a point I hadn't considered, which was "What era is this in".
Since I hadn't thought about it before I decided to look for hotel(s) /(rooms) in the 1900's, I narrowed it down by finding out when one of the first detective books where written which happened to be 1920.
I chose the "Detective Era" because the games (I.e. Hotel Dusk, Last Window of Cape West
) I have seen which go in that area have the most lovely dated furniture and wallpaper, it has such atmosphere hence why its a background influence.
I found pictures of rooms from 1920, and some pictures of outside random hotels, I do not however think I'll be doing an outside piece. Some of these pictures I like because of their almost flat and dull color and would like to incorporate it in my concept art if possible.
