Cal here from Shopify, thanks for reaching out to us. I can see that the Community has provided some awesome feedback on your store for you to consider. I thought I'd add a few points from my own experience on your store:
I agree with the suggestions above, that you should avoid paying for ads for now, and try to get some organic sales. I would take a step back, work on marketing personas, and develop a great marketing plan once you know who your customers are and what problem you are solving for them.
