Hello, Yeshuas Child,
I noticed that you are not using all 13 of the tags that you are allowed. I think that is why you are not getting views on your items. You could use terms like wall art, oil painting, bird art, bird painting,... basicly, the sort of phrases that buyers would type into the search bar when seeking art of your style. You also have a very small number of listings, the more items you have in your shop, the more likely you will be to show up in a shopper's search. Maybe you could list the original paintings. While original paintings are not big sellers here on etsy, I know that I, for one enjoy browsing them, and browsing brings eyes to your shop. If that means a thousand dollar price tag, remember that the person that clicks on your painting probably won't buy it, but they just might purchase a print of it instead. Especially if, at the end of the description they read something like, "if you'd like to purchase a print of my work, you'll find it here - " followed by a link to your listing for the print.
Also, I would also like to gently suggest that you change your "shop owner" name to your first name. People like to picture the individual that created an artwork, and seeing the name Sheri will help them to do that.
Your work is really lovely, and people love imagery of birds. If you maximize your visibility you should be able to sell your very beautiful cards :)
