Do you own the rights to the modeled photos? I'm not sure if using pictures that you pulled off the Internet is Etsy kosher. I could be wrong, but you might want to check on that. I personally think you should nix those photos altogether. Although they are pretty, when I browse a shop I want to see photos of the actual items. Try taking pictures of your bottles in natural light or look up how to make a simple light box.
Also, I would keep researching about SEO tags. In most of your listings you have the size of the bottle, the name you've given the scent, and some other non-searchable details that are taking up precious space. The first few words are essential in helping customers find your items and nobody is going to be searching for the size of the bottle or for a name you have given the scent. You want your titles to be something like "natural perfume oil women's fragrance almond peach night flower MERMAID 25 ml" I know it looks funny but if you do it right it really does bring more traffic to your shop.
