HI Zoe,
You make fantastic, intricately designed jewelry and I love them. Now from my perspective as a "shopper", the items just don't pop off the page for me. I've seen a bunch of advice on using white background, but I my opinion, that only seems to work with large, colorful items. The leaves and twigs you show with the item really doesn't do much if you're trying to indicate some sort of size relationship. The leaves and branches could be any size...I just don't know. I personally think if the items were actually modeled, then I could get a truer perspective of how they look on a person, and more effective size relevancy. Also, I agree with Kathleen, include a chain. I find it very annoying when I have to shop for two items to make one gift! It is well worth my time to pay the extra few dollars to get a complete accessory.
Your prices are great, maybe a bit underpriced considering the time and attention to detail you give your items, but adding the chain will give you incentive to raise your prices slightly without feeling guilty doing so.
I hope I'm not being too harsh or picky, but you're off to a great start. I do honestly love your jewelry.
Bear Hugs and Happy Sewing,
Roanne
