Overall I think your shopify store looks pretty good, But I noticed a couple of things that you might consider adding.
You might consider adding an always visible buy button. Your buy button is the most important button on your site and it should always be within the thumbs reach of the customer. Take a look at your store (especially on your phone), and try to easily find your buy button, especially when you are on the bottom of the page. If your buy button isn't always visible you are making it harder for your customer to buy. Consider adding https://apps.shopify.com/better-sticky-checkout-button-increase-your-sales , it will help it make it easier for your customer to buy from you.
An important thing I couldn't find is social media links. Adding social media for your store can go a long way in fostering a brand
I wasn't able to find reviews. It would be good to add reviews for your products. Think about it when was the last time you bought a product without reading the reviews first? I think you should definitely add some reviews.
Also I noticed that you don't have a FAQ section. Adding an FAQ section to your store can help your customer more easily be able to find a solution to their problems without asking you. This will help long into the future so you don't need to spend so much time on customer support
You might consider adding a blog. If you had a blog you would be able to drive more organic traffic to your store, plus it would help establish yourself as an expert.
You might consider adding a sense of urgency. One of the main reasons why people don't buy from a store is because they feel like they can buy it whenever. A big thing that can help more of your visitors be turned into buyers would be by adding a sense of urgency to your store. One way to add urgency is to have a sale, and all sales need an end date. You can easily add a sale to your store with a countdown timer. One countdown timer that I recommend is https://apps.shopify.com/better-countdown .
You know your store is actually quite good, and I think with just a bit of love and care, you will be able to really succeed.
Just so you know (I had to do it), I wrote a series of emails https://mailchi.mp/7d8692283c12/shopify-conversion-course that might help you with some tips for making your store better (I get into the weeds there).
