My reluctance comes from being very much a beginner so who am I to offer advice, but on the other hand what if my 2 cents worth can help someone who also is not so advanced and what if no one is offering feedback? So, I try. We should all chip in.
Beginner or not, you are as entitled to your opinion as anyone else as to why a picture works or not.
I was watching a program about wine a few years ago presented by an international 'Master of Wine' and she said that her training enables her to express what she tastes in standard language. Whether a wine is good or not is a personal opinion.
I take photo critique in the same way.
If you are a member of a photo club, it can be bewildering why the same photo can get 20/20 with one judge but 14/20 with another. Odd, but a fact of life.
