Great concept Anna. Hadn't thought of using multiple pieces together. It looks like a real room. Just a little too cluttered though. I don't think it would translate well on to business cards, signs, etc. We were looking for a cleaner look.
This art, though looks hand drawn (which it was) is actually all vector objects that can be separated into pieces and used alone or in combination with each other.
Certainly eliminating details is easier than adding them ;)
