I've come to realize that there are two types of shoppers on Etsy: those who favorite and those who buy. Very rarely does a favoriter become a buyer in my shop- so you're not alone on that front.
I wouldn't lower your prices, but could you offer more different products in the lower price range? Maybe build up some new products to offer in that line? Could you make a cheaper version of your most popular items, maybe from different materials, with less labor, not as ornate?
The other thing I noticed about your prices is that they look pretty variable when converted to US dollars. Most Etsy sellers are priced at whole Dollars, or $1.99, so seeing your pricing all over the place is mysterious. In stores when we see things that are marked $123.23, it's usually on sale or clearance. Maybe experiment with having your pricing in round $ for US buyers, just to see if that makes any difference.
Try different tags and see if that makes a difference in views. I've been experimenting with different titles and that's really expanded my reach. Just play around and call it market research.
