Revisions exist because nobody describes what they want accurately the first time. That is normal, and the process should expect it rather than charge for it.
The first version is a starting point. Almost nobody can describe the logo or design they want before seeing something — reacting is far easier than specifying.
That's why the revision stage is where most of the actual improvement happens, and why capping it at "three rounds" pushes people to accept something they don't love.
Less useful: "I don't like it." "Make it pop." "Try something else."
More useful: "It reads as too corporate — our customers are homeowners, not offices." "The mark works but the name is hard to read at small size." "I like the second one but the color feels cold."
Describing the problem lets the solution come from the person doing the work. Prescribing a fix often solves the wrong thing.
