Simply saying “it doesn’t feel right” isn’t sufficient feedback when reviewing a design with a manager or prototyper or engineer (much less so for other peer designers). It’s just a recipe for communication breakdown, with misinterpretation and ambiguity creating problems of what was really meant.
Gotta be specific–is it the spacing, the layout, the color, the type, the behavior, etc. Get it down to the specific design signals/variables that is the source of the problem or difficulty–then a productive conversation and more importantly, action, can follow that helps everyone get on the same page and towards resolution.
Else, team breakdowns can result, all over a simple misunderstanding that causes people to try to fix other things that cause breakages to occur in the design, etc.
