I think you have a nice product. But, for a lot of them, I couldn't tell what the product was by looking at the picture. I would suggest zooming out a bit - and as Julia suggested, I think the pics that feature a model would do much better as the main image.
For example, this product:
https://www.etsy.com/listing/155636595/wedding-fascinator-crown-woodland-floralI can't tell what it is by looking at the picture. The 2nd or 4th pic would do much better as a main image, in my opinion.
Also, definitely add many many more tags. You should use up all the spaces for tags. And be sure to use multi-word tags as well (whatever people would search for). Just looking at this one product I just linked to, it doesn't seem to have any tags.
Also, instead of saying this:
"The crown in the image is for reference only and not for sale. A new one will be made and sent at the time of purchase."
...you can just say the product is made-to-order.
