Hi Nicole! I love your art - it's so fun to look at all of the elements that make up the complete picture. There is so much to do in order to be found here on Etsy. The best thing to do is to join the team - Beginner SEO. They will help with suggestions to make your shop more visible.
I see that you have your original paintings for sale, but no prints. I'm sure if you could have your originals printed onto paper you would see an increase in sales - as the prints would be affordable to everyone. Making sales every day or week will increase your visibility here - which will make it easier to sell your originals.
I love drawing Corgis. They have such great smiles. I've never known one personally, but they seem like such a happy little dog and totally comfortable in their short little legs:)
