It’s really tough to say; you are not using your photos in quite the same way as for instance; I would. That’s not a bad thing just completely different medium.
I really like the main shot here; and it was the typewriter seen from your main page that made me click on it.
https://www.etsy.com/listing/159951034/the-brave-one-typewriter-quote-on-25-x-5?Many of your listings are text on paper in the store; and I “felt” that many were tilted, or not square but that’s a carpenter thing. The crooked text really works when I see it in its environment. Maybe put the tags on a prop or two like a crate or a suitcase to draw my eye. Having one straight on clear and easy to read shot is good but not giving me any ideas. Your photos are clear and well lit which still kicks my butt.
Try adding some flavor, show me what it is that I could do with your product; show me why I want it. Don’t be afraid of the customer needing to click “enlarge” on a few of your photos. Personally I like the muted tones that are common in your listings; but I also know what value to place on my tastes in things.
I like the tags a lot; now if I could get a poster-ish size tag. Not really a poster but larger and still maintaining the roughness. ;-)
I know all things in good time.
I hope this helps; and I hope others will chime in with some better thoughts and Ideas.
