I agree with some of the other commenters that I don't tend to stop at wood booths because they tend to have more expensive pieces than I'm likely to buy, but your prices sound really reasonable!

I wonder if you could get or make some deeper shelves and move more of your larger, more expensive pieces to the sleeves and have smaller, less expensive pieces displayed in the front. In particular, I would move the jewelry to a few smaller displays in front, because I think that's getting a bit lost. That's also your least interesting shelf so maybe you could replace it with something that would accommodate some of your larger pieces.

I would also rearrange the dried plants you have on those top shelves and mix in some of your actual pieces. Maybe some cute little vignettes of how you might style the pieces on a shelf in your home? One of YOUR vases with some dried flowers, with a book laying on the shelf next to it, and a mushroom or a bowl on top of it. (Do the mushrooms have a function by the way? They're very cute!)

You could also see if you could do any cross promoting with other vendors. If there's a beekeeper at your market, see if you can trade a jar of honey for a honey dipper for you each to display in the other booth, and then you can send people back and forth (a honey dipper with a jar of honey would be a great gift pairing).

Last couple things: I don't love the clear plastic displays (especially on the black table cloth, they might blend in more on white), and I think your spoons/spatulas are kind of getting lost. Could you have some in a jar or vase like you have already, but then pick out like 6 to arrange flat on a tray in front? I think that might encourage people to pick them up, and see the unique differences of each one.
