I'm happy to provide you with some feedback on your store and help with any marketing strategies you may be struggling with as well!
When I view your store, there is no information on your brand, no logo, no shipping and return details or contact information. These are all extremely important things to have on your store, as without them, there is no trust between the customer and your business. Without any idea of who they're purchasing from, your potential customers may be extra cautious to order from you.
I think these points are the most important for first setting up your store, since not having these trust points can be detrimental to your business. I understand how it can be hard to earn that trust from your customers without any sales, but you can find some more great pointers to help out with this right here.
On a separate note, I'd be curious to know which marketing tactics you have tried so far? I see that you have a Facebook page linked in your footer, which is great! Have you done any advertising on there and seen any traffic come in as a result? I'm happy to discuss what you've tried already to provide you with some strategies that could work!
