Love the center area but found the border just a little too different from what I remember the Geiger style conduits and tubes were like in the walls in the movies. They were much fatter in the movies and his artwork. This border looks more like a plant - ivy or similar in that it's features are finer. I wonder if copying the Geiger style is not allowed. Overall I'd be happy to have it in my home.
At the end of the day, gameplay, sounds, and theme integration are the most important. There are thousands of graphic designers who can do this type of art - but only a handful of people who can make a killer game.
