Your boxes are really beautiful. As for your buyers, I am sure they would like to know your policies, what happens if an item gets damaged in shipping return and refund info, things like that. Check out other shops policies to get ideas of what to include.
Also work on your tags and titles, use more than one word in each tag, some suggestions off the top of my head... simple things that people would use to search for your items, "Magpie art box", "fantasy gifts" , "spiritual gifts", "jewelry box" "keepsake box" "Gothic art" "raven accessories" The better tags you have the easier it is for people to find your items. Good luck!
