Facebook ads guidence to get sales for my jewelery shopify store

Okay so I am 18 years old. This is my second store and there is no issue of how the store is or the products. The products are unique and have good profit margin and the store is also very good. What i am lacking is in marketing department. I have created and ran facebook carousal ads as they allow me to show a number of products at once.
I know much about the ads but am lacking something. I did Targeted audience for 43$ and then went general yesturday. I have shared images of the ads I am running right now along with my website link.
Please analyze it and let me what should I change.
Thank you!
