I am using all of them Wayne. I work in a lot of different...I don't know if you'd call them styles or genre. And sometimes I mix them both together. In fact, I'm usually trying to marry the two in some way. I feel those are the most successful ones (if I can manage to do it).
The wall is going to be crammed with a lot of random things: preliminary sketches, maps, articles, post-it notes with coordinates and little sloppy drawings, postcards, photographs, survey/plat maps, more rendered drawings, abstract drawings, "for sale" signs, etc. They'll all be tacked to the wall willy-nilly using thumb tacks, sewing pins, band-aids, and tape. All of it is desert-based regarding the land around here.
