Cal here from Shopify, thanks for reaching out to us. Welcome to Shopify, you've done some amazing work so far on the site!
I'll keep it relatively light, so you can implement some changes and then come back for more when they're done.
- Get yourself a Favicon for your browser tabs, you can edit this in your theme editor.
- The landing page is too text-heavy. Think of the landing page as a portal to the entire site, right now you are blasting your customers with text, which many customers won't be able to give the time to read. And consider also that many of your customers might be on mobile devices, and all this text would take them forever to read! You can create separate pages for a lot of this text content.
- I think your navigation is a little busy. Is there a way to structure this with more sub-headings in the navigation?
- Some product reviews or testimonials on the site would be a great addition, as the business is so new! This will help your customers trust your business more.
How are you marketing the business currently? Who is your target audience?
