Art Festival Booth Critique?




I've been doing art festivals for years, but I feel like it's time to level-up my booth display. Here are a few photos of my booth at Boylan Heights ArtWalk in Raleigh, NC last December. (It's one of my best shows every year!)
How can I go from "arts & crafts artist" to "serious fine artist"? Thanks for your help!

I use wooden lattice panels, available in all garden centers, and plastic ties to fix the plants to stakes to hang the paintings on them. It doesn't cost much and it's very effective. All of it under a canopy to protect from sun and rain (about 120 euros).
Those look very nice! Thanks for sharing this tip and your photo!
