My name is Lizzy and I’m from the support team at Shopify.
I noticed in the title of your post you've mentioned feedback on your store. I'd be happy to take a look and offer some thoughts. Please could you share your link here so that I could take a look?
In regards to your question about the sections quoting "talk about your business" and "Share store details". It sounds like these are from sections you have on your home page. Does that sound right? If so, you'll be able to adjust these in the theme customizer. You can get to that spot by going to Online Store>Themes>Customize (on your current theme). In here you'll be able to see your editing tools on the left, and a preview of your store on the right. Like this!
Let me know if that helps to update those spots!
