AIGA | How to Survive a Critique: A Guide to Giving and Receiving Feedback.
Listen: Keep an open mind and avoid being defensive
It can be painful to hear critical or even negative comments about your work, but the most important thing you can do during the critique is listen. You want to be aware of all the different reactions people have to your work, both good and bad. Most importantly, you want to understand why people respond the way they do. This information will enable you to adjust and revise your design with the goal of making it more successful.
Avoid getting defensive. You don’t have to justify your work—arguing makes you seem unwilling to accept input. Try to stay calm. If anger management is a problem, plan in advance. If necessary, make a voodoo doll that you can stab when you get home!
