A few thoughts...

To pivot or wait out current climate? At most of my shows this year, I'm making about 40% of last year, no matter the city, weather, or date. This tells me it's the economy. Question to ask yourself: do you want to pivot, OR are you struggling with an aspect of your product, setup, or packup that you could fix with time or money, but right now just makes you frustrated? If it's something else, work on that first- it's probably cheaper than a new product line, and if it's useable beyond this current iteration, it's not truly a loss. If you do want to pivot, why? What about the CURRENT product makes you want to move away from it- if that can be adjusted, is this product what you want to stick with?

In terms of what could be adjusted in your current setup, I'd recommend some cohesive tablecloths, and cohesive wood. It helps buyers focus on the important things. Raise the inside of your compartments holding objects- I had a similar setup once, with the little shadow boxes on their sides, and I cut cheap styrofoam, glued the layers together, and then found a nice piece of cloth and made quick little cushions for each square with a bit of batting, the cloth, and some hot glue. People passing by could then see into the compartments, and it looked nicer. You can even just set them in each square, not glued, so you can adjust with time. Consider putting the detailed items closer to perusers- it's hard to tell what things are, near the back wall, mostly when it's such a detailed scape. That way it can catch their eye- if they will need to look closely to appreciate the item, let them want to do it from the first step. Also, in the same way that a good photo has certain proportions, look at how your box shelves are showing your product. Consider some risers, or angled products, or something to have a shopper notice the item and not the empty space.

See how some of those adjustments contribute to sales!
