Her feet are quite attractive, but I require some close-up images to fully appreciate them and provide an accurate rating. For now, I’m giving four stars, pending the arrival of high-quality close-ups.

BigToe81, I often use your approach as well. I can easily see that her feet are likely much better than most (4 stars) but I really need to be more sure that they are great (5 stars) and more "definitive" shots may be required to convince me of that. Rather than asking for a "6th star" (which would be abused in no time as well), I just want to make 5 stars to be more special, a little more exclusive, not assumed or routine
