Looking at the Appraisal gallery, it seems to me that almost all suggestions about how to "improve" pictures fall into one of two categories. One category is that the potential for improvements is to a greater or lesser extent obvious, so that more experienced photographers can genuinely and fairly easily help. The other is that the suggestions actually detract from the picture, and the main problem is that the photographer lacks the self confidence to realize just how good they are. I say "main" because a subsidiary problem is often that the person offering the suggestion is stronger in confidence than in ability or knowledge: they are commenting because they think they can, not because they have anything useful to say. Whenever anyone criticizes one of your pictures, ask yourself what category their reply falls into. Consider also that the first version of a picture will almost always have the greatest impact, so that a minor "improvement" may not look as good as a (slightly defective) original. In other words, have more confidence in yourself than in the opinions of others, unless your immediate and almost instinctive reaction is "Of course!" If it's "Well, yes, I suppose they might have a point," then they probably haven't. Cheers, R.
