I have yet to see many Juried Contests that have much of a "Good Jury". I know when I used to enter them, I would see these pieces that were so outstanding, I knew I had no chance against them. But the problem was, they, like, did not win, and I did not expect to after seeing them. What usually wins, is some piece that looks like it came from a Kinder class. I felt so sorry for the ones that had such excellent pieces, that I knew if I ever got that good, mine would be no different. So I just quit trying in them, and just kept working on my skills.
Now I have had some luck in my poetry, having five national and international awards. But even then, I have seen some real pitiful ones win too, and some really beautiful pieces lose. It just makes no sense to me to keep trying in them. I will from time to time look through a few contests, and again see some wonderful pieces that do not win, and some pieces that win, that make you wonder what the judges were smoking.
