Cal here from Shopify, thanks for reaching out to us. It's a cool looking website, you've done some great work. I'm just curious about where the source of your traffic is coming from? Likely, if they are bouncing away, they are not the high-quality traffic you are searching for.
If you gave the community a rough idea of how you are currently marketing your business we may be able to make some suggestions on why it appears customers are bouncing off the site. Do you find that they are adding products to the cart?
If you haven't developed a marketing plan, I strongly suggest drafting one. Who is your core audience? Have you identified their interests and behaviors?
