Nice job on your store. Honestly it's quite good, I like it a lot. There are a few tiny things I would change.
After carefully reviewing I don't see a FAQ section. Customers often times will want a lot of information before they make a decision to purchase. Adding an FAQ section with information about things like shipping rates, returns, and anything else relevant can help your customer more easily make a decision to purchase
After browsing your store I noticed I wasn't able to find a sense of urgency. Imagine you are a customer browsing an online store. Maybe you are ready to buy maybe you aren't. But there is a good chance you aren't in the buying mood at the moment. If you add a sense of urgency to your store it can help more of your customers to buy, and have them buy faster. One way you can do so is by adding https://apps.shopify.com/better-countdown .
After browsing your store I noticed I wasn't able to find a blog. If you had a blog more customers might be able to find your site, and even if they aren't ready to buy at the moment they are reading your blog, they are more likely to buy from you in the future.
An important thing I couldn't find is 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.
After browsing your store I noticed I wasn't able to find reviews. If you add reviews it will help keep your customers on your site. If your customer needs to leave your site to do research on a product they might not come back, adding reviews can help with that.
Overall your store looks really good, I think with just a little bit of time and effort you'll be able to create a really awesome store!
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).
