Honestly, I don't think it's priced badly at all. I can tell just by looking at some of your items that they are very nice. I wouldn't say your prices are too low, I'd say they are really reasonable. I've often wondered the same about my prices as well... I think the best advice I can give you is to play around with it. Check how many views and favorites you are getting now and raise a few prices to see if it changes at all. That might be a good way to start? But in my opinion, they look fine. :)
