It seemed to me that the teacher warned the children too much about the shortcomings, and on the contrary, she did not comment at all on the successful work. Maybe because in these cases she had nothing to complain about the students. Although I don't think the quality of the images is any different. I also think that the role of a teacher is not just to correct pupils and point them out to mistakes.
