Most people find it hard to say what they don't like about a design, especially when they can't say why. The good news is you don't need design words. You just need to be specific about what you notice.
Say what you see and how it feels
"It feels too serious for our audience" helps a designer much more than "I don't like it". Describe the feeling, not the fix. Let the designer solve it.
Start with what's working
Tell us what you do like. It keeps those parts safe while we change the rest.
Collect everyone's comments first
When several people are involved, gather their feedback into one message before sending it. Conflicting comments sent one at a time slow everything down.
Connect it to the goal
Remind us who the design is for and what it should do. "Older customers need to read this from a distance" gives us something real to work with.
Point, don't just describe
- Circle or number the parts you mean on a screenshot
- Send examples of what you have in mind, and what you don't
- Tell us which comments matter most
A round of feedback with a clear goal will usually get you closer than three rounds of vague ones.
