As artists, we are constantly looking at each others work, giving critiques, and receiving critiques, which can sometimes be difficult and painful to hear. We spend so much time and effort on our work, that when we receive critiques, we have a natural reaction to defend ourselves and our work. But if we can suppress that urge to defend ourselves, and let ourselves be vulnerable, be open to what others are saying, and know that they are not trying to tear you down, but to help build you up, you will be on your way to becoming a better artist.
That's what we are all doing here right? Striving to be better, to do better, to grow and learn as men and women. If everyone is working towards the same goal of becoming better, and if you can let yourself be open and vulnerable when you are receiving a critique, there is no telling how much you will be able to grow and learn.
