1. Density
"This design is bad" is ironically bad advice in of itself. The litmus test of good feedback is if it's recipient can instantly act upon it.
However, pushing too much prescriptive feedback is pointless as well. It kills the resource's creativity and diminishes trust.
2. Timing
I know managers that will start flipping out when someone's just created an outline or draft. Giving feedback too soon shows impatience.
However, a pure "waterfall" mindset isn't great either. It's best to check in before the deadline to course-correct if needed.
3. Tonality
Tone-deaf feedback can be misleading.
If you have 5 points and some have greater priority and urgency than others, make that obvious.
Similarly, clarify if your feedback is a deal breaker or exploratory.
4. Knowing when to stop
Arguably the toughest of them all.
Over-engineering something can be counter-productive. Nothing will ever be perfect.
Sometimes a few imperfections in the interest of time-to-market is a better bargain.
Also, don't give feedback for feedback's sake.
