Hi Sophie,
Some of your tags are pretty good e.g. black and white view finder photograph. They are multi-word and cover different search terms. Apart from "print" (which you've repeated several times), you can also try "wall art', "home decor", "office decoration", etc. Think of synonyms and related search terms.
"Paving Paradise" on the other hand has all single word tags, which you can replace with multi-word phrases. In addition, the title should also say what the item you're selling is. Include more keywords in the title for search-ablility.
Hope this helps and good luck with your shop!
