I totally get where you’re coming from! From my experience working with mural artists, a good middle ground is usually built into their standard terms. For example, I recently checked a New York-based service ( city design projects https://feelflow.space/pages/mural-painting-services-in-new-york) where they provide 3 rounds of digital sketches, 2-3 sketch revisions on the wall, and 1-2 minor changes during the painting itself. This setup gives you enough flexibility to tweak your design without causing delays or inflating the budget. Personally, I liked having the digital sketches first because it made it easy to communicate exactly what I wanted before they started painting. It also helped prevent misunderstandings about colors, composition, or scale. Honestly, it made the whole process feel structured yet collaborative. So I’d say, aim for a set number of revisions that balances your creative input with the artist’s workflow. That way, everyone stays on the same page and the final mural comes out exactly how you imagined it.
