Are you saying that, on a good day, you give everyone an "excellent"? Perhaps you're just being more honest. Your mood certainly will affect how you perceive a lot of things. Even if someone has "ratings" turned on, I sometimes don't- what I see as excellent is someone elses good or great. If someone takes the time to comment on a picure, it means they at least took the time to look at it closely and thought it over enough to have an opinion, rather than just ignoring it. I'm not sure I understand why there are ratings- this site has so much stuff posted from beginners to serious artists- how can you grade them all by a single "yardstick"?
