I just checked out your shop. Lovely pieces! I think your prices are amazing. I think though, you might not be among your target audience. I bet they are looking for more traditional jewelry. Have you considered vending at Rennisance Faires? Chainmaille does quite well there.
I tried Artfire a couple of years ago around the same time I started my Etsy site. I had a lot more sales on Etsy so ditched my Artfire account. However, I think I'm going to give it another go and see what happens.
