Taltos,
That's odd you bringing this up. A friend of mine was over recently, and was looking at some of my photography as well as some of my acrylics that I keep laying around in my spare junk/bedroom. She kept on about that I should hang my stuff up where people that come over can see it. I've never really given it much thought as the majority of my stuff doesn't fit in with the decor anyway, but I guess
if your girlfriend thinks enough of your work to be able to look at it all the time on the walls, go for it. I myself am my biggest critic. If I had to look at my stuff all the time, I go nuts thinking about well if I had shot this this way and that.
