Hey there,
I love the fun little teacup rings especially.
I know this space is more of a critique for the art, but I think it would really help if your items were on consistent backgrounds. Some of the earrings get washed out and don't look as "nice" as they could with a yellow-ish background. Yellow is typically a colour that can get scary very quickly, so maybe you could find a paper backdrop that would have the same feel, but more white? Or if you have Photoshop, you can go in to Adjustments > Selective Colour > Select White > Pull Yellow slider down to reduce yellow
Hope that helped! Cute shop items!
