Congratulations, you have some nice designs!
The first thing about your shop that strikes me is the big banner shop image. It's a lovely photo of your illustration, but I look at this and I think " she is an illustrator" not "she sells badges." And (yes, of course you are an illustrator, and a good one too I think!) but because here you are selling badges, I think you need to be really clear about the product you are selling : the buyers need to look at this and instantly think "I can buy badges here". I think you need to add some photos of the pins/badges into that image, maybe scattered on the left, maybe on a white background, then reset your name and social info around them?
I also agree with RetroDoDa,
photo of them being worn
photo of being held in hand so you can see size easily, are both good.
As far as the pins themselves: are you selling them in the real world- did you try to sell them in shops or markets? This type of real-world feedback - not just from friends, but from people who don't know you- can be really helpful. I understand that is hard to do at first, and puts you outside your confort zone, but it's worth it, and this type of real- world feedback will really teach you what people want, and what they want to see more of, and you will grow and learn faster than you ever expected. Good luck!
