Hi there! Maggie, Shopify Expert here :)
Congratulations on a brand new store - it's a great niche and I definitely recognize some of these products from the Shark Tank :) Your images are good quality - make sure to keep an eye on the little details - I saw that one of your collections is missing the featured image:
It's a small thing, but it can actually make an impression the store is not looked after [i.e. perhaps no longer operating], which might negatively affect your conversion rate. Hope it helps!
