Hi Wendy!
Just started checking your shop out. I do not think that something is totally wrong with it, and your sales are proving the opposite.
I am a newbie with only 2 sales, can't really give advice to you. Just a few things:
https://www.etsy.com/listing/91583443/vintage-sixties-pink-pose-doll-also?As we are taught here - what is it? Doll - must be in the first 3 words in the title. Your shop is all vintage, and this word will pop up from the categories, no need to use the front space for it.
What if you put it as Pink sixties doll Little Miss Know it all? You can play with titles and tags and see what happens.
https://www.etsy.com/listing/95878054/handmade-vintage-gemstone-and-brass?I really loved this little guy too!
Again, I would call it Labradorite Gemstone Spider, Jewelry prop, home decor. Makes sense? From a gemstone seller point of view, I would use the stone name in front, collectors may look for it.
I must apologize again, I am not playing a know it all here :) Just try changing some titles to see if it brings more views.
Your shop is great, especially I love the way you titled shop sections! Even grey carpet background didnt chase me off because it fit pretty well with some stuff like axe and your other "Weird and beautiful" things.
And you have so many items! I just want to look and look! Tags sound good to me, from those I checked.
Wishing you more helpful advice and many views and sales!
