Mel has made a great point there. It's good to have a range of prices through your shop as well as items you can make again and again. Have simple things, have complex things, see what items are trending, try to get your items trending, look for craft fairs or local events or galleries you can also sell your work at.
There are still lots of things you can continue honing in your shop. If it makes you feel any better, I've had barely any sales on Etsy for the past few months. However, I've been working on my inventory for Christmas and upcoming craft fairs. I've also applied to a local gallery and have a number of my jewellery items on display. I think a gallery would be a perfect place to show off the incredible detail of your work. Your photos would only need to be for a portfolio then instead of touched up and listed etc.
Give it a try- seriously! You're located in Bath, right? Give this place a look:
