Tom, we have the choice when we start a new thread to state whether we want a critical discussion. The three categories are Critique Required, Critique Welcomed, and Just For Show. I've never once (if I remember correctly) used these prefixes, as I don't mind if people want to criticise or applaud; either way this is the photo I have chosen to share.
I don't mind constructive criticism, and have learned a lot from those who have kindly offered the benefit of their experience.
When you say, "Personally I feel there is a little too much of the image in darkness", that did not strike me as constructive criticism, or even an invitation to debate. It is just your personal feeling. I respect you for it, and feel no need or compulsion to question or challenge it. Nor did I feel a need to defend my aesthetic choices.
I learned through being a musician that you can only please some of the people some of the time, so I never ever try to change people's minds, bring them round to my way of thinking. If I don't like something I see in someone's photos, I try to be positive in my own images, let my work say how I think things should be.
