Thank you for your input. But do know, in life to be great at something, we need to learned to accept our failures. That goes for photography. It's great to be praised for a few photos. But she would never get better if never critiqued for the wrong. How can she learn, get better if she doesn't ask for advise?
Just as you gave given, are well points that she will take and use to perfect her skills over time. So thank you. No need to have a thick skin, just been open minded and use all critiques to better her.
