I can understand that you don't like the photo but how dare you say that these people are unappealing? And who are you to despise others? So, only "appealing" people should be photographed? Anyway, what is "appealing"? If you consider yourself a photographer, you should also consider tossing away any idea of judgement regarding your potential subjects.
That said, I must thank you for this; now I know where I stand: far away from the current aestheticism in photography, where photos must be "appealing" instead of sincere. What you meant is that I should have photographed these "unappealing" people in a way that make them look appealing. I'm glad I didn't and I hope I never will. Goodbye.
