I see that you do have some sales now and plenty of people are loving your stuff! I don't have very many sales myself yet, so maybe am not in a positon to advise you.
But I have noticed that the more items I post for sale the more sales I have. I have been on Etsy for a few years with just a few items (about ten) listed and didn't get any bites, but once I increased my listings, I started to get the sales. That's my new strategy anyway :) Plus it's fun!
Love your charms!
