Bhargava,
We all make suboptimal decisions. On hind sight we know that we could have done better. Honest critiques are important, so that these things are there in your mind and when you shoot next time your subconscious mind tells you to move left or right or change a setting.

I have been photographing for a long time and have made lot of mistakes. Even today I make mistakes.

These days even CEOS have a one-to-one coach so that they can learn. So take the suggestions in your strides. The idea is to learn and improve everyday.

Cheers,
Sabyasachi
