Maggie and Sam,
Your photos are both amazing, I'm so jealous. SEO is never ending, but the one tip I can give is to look at your shop info in terms of search engines. Borrowing from the Relevancy SEO team:

It's been a while since we talked about this so I want to remind people that google crawls your whole shop and your shop title, announcement and section names are very important to your SEO.
The same rules apply. Use your strongest keywords without breaking up the phrases at all and take advantage of the opportunity to use the plural forms of your keywords because they usually have higher counts than the singular forms. Even though we have limited space try to remember that google isn't a human and won't make obvious human connections. "Silver necklaces and bracelets" isn't as good as "silver necklaces, silver bracelets". It's also important to remember to leave a space before or after your punctuation.
(Shop title is the phrase directly below your shop name, and the way I saw it explained, describe exactly what you sell in your shop title, and once you set it, avoid changing it again because it breaks the links google makes to your shop.
