Hello Anna
Hope you find this feedback useful, I will only point out the shortcomings here and leave the good part aside for now.
1) The "About Shop" on the top below the Pink Pather Arts panel is very generic and does not carry much info about the shop and the idea behind it or the vision of it. I think you could spend some time on defining that part more precisely.
2) No. of products are just 15 which is less. You need to have more products.
3) Different categories needed. Your shop just has one category "Prints". Categorising paintings under various categories like "Nature Prints" "For Office" "Livingroom" "Tabletop" etc will help clients decide what they want. And direct them to the category that suits their purpose.
4) Each print should carry a small writeup about the print. The idea behind it. For eg. in this one
https://www.etsy.com/in-en/listing/264531503/baby-on-the-moon-nursery-decor-nursery?ref=shop_home_ac..."A painting for the baby's room. This was concieved when a friend of mine had a baby and wanted something to put on her room."
This is just an example, but this will create a little more involvement of the prospective buyer.
My View.
All the best and happy etsying.
