You are using PP template? I suggest you after apply the same template, readjust the exposure as different picture have different exposure and brightness.

Of course everyone has very own eye sight and opinion. But in order to produce a great photo, which major people agree that that's a great photo, there's some certainty for the criteria.

Well it's up to you anyway. Photographer taste is unique, but criteria for a fantastic picture by everyone is almost the same. So it depends on you want to make it fantastic for everyone, or just you
