Things I would change are not unlike what others have said. I'd definitely change out the fluorescent overheads to one or two tall, glowing lamps. I think that would actually have huge effect on how I feel in there (more safe and relaxed), not just the overall aesthetic.

If not the lights, then the couch. She has a very luxurious, soft love seat in there right now, which I do like. But sometimes I wish it were one of those classic, psychoanalytic fainting couches so that I could completely lay down and regress a little. Might as well throw in a Persian carpet while I'm at it.
