Very good article.

I would like to add the following elements:

Talk about the actual design and avoid generalizations. For example, instead of saying "I don't like this color", say "This color is too bright and distracts from the main content". This way, you are describing what you see and how it affects the design, rather than expressing your personal preference.

Be objective and focus on the work, not the person who created it. Don't make assumptions about the designer's intentions or motivations, and don't use words like "you" or "your". For example, instead of saying "You didn't consider the user's needs", say "This design does not address the user's needs". This way, you are giving feedback on the design problem, not the designer's performance.

Design critiques are usually filled with negative and positive feedback. The environment is created to encourage constructive criticism. However, it can also be stressful and demoralizing for the designer who is presenting their work. Therefore, it is important to practice gratitude and appreciate the effort and courage that goes into sharing one's work. For example, you can start or end your feedback with a positive comment, such as "Thank you for sharing this design with us" or "I really like how you used this animation". This way, you are showing respect and recognition for the designer's work.
