Everyone comes in contact with critiques and criticisms at some point in life. When you're under critique, it's good to remember a few things:
1) What you think about my work does not define me. I don't have to build my character house on the foundation of your opinions.
2) My style isn't wrong just because it's not how you would have done it. Compare Shakespeare to Dr. Suess—surely one wouldn't have liked the other's style, yet each is a master in his own right.
3) A little bit goes a long way. Don't dwell on the negative criticisms you receive, or you'll see them as truth. Don't just listen to the people who constantly sing your praise, or you'll earn an inflated ego and an inability to see your own mistakes. Hear criticism, evaluate it, and let it go. The past is the past, and you don't owe it anything.
4) You always have something to learn. In the vein of a humble and teachable spirit, listen carefully for the lesson in every critique. It could help your art, your style, or just your ability to critique someone else well.
5) Graciousness is king. It's hard to smile and say thank you when you hear something negative about your work—but the people who are willing to tell you the negative things deserve commendation for their honesty. And even though you may not want to hear how your work is missing the mark, it may help in the long run. No matter if it's off base, unfair, or poorly delivered, say thank you. In anything from a sticky to an explosive situation, it builds relational equity. And we all need more of that.
And, most of all, remember Who you do your work for, and what He thinks of you.
