Zoe; look at your prices. They're all very low on the prints. (Since I don't do originals, I can't speak on those prices.) Your art is priced lower than my photographs, which I'm not sure should be the case. When you got a 30 inch print, the prices should be close to or at three digits before the decimal point. If you don't value your art, no one else will either. Go through similar portfolios as to yours, click "Art Print" then click "Show Price Details" to get an idea what people are selling for her.
