All photographers voting on photos are using different evaluative criteria - no consistency. Weighted voting helps a little. Too many submissions are off topic; for example, participants don't seem to know what complementary colors are or the difference between a profile and a full front or 3/4 view. Contest designers frequently ask participants in their contests to "be creative" but the more creative your entries are the fewer points they score. I am both a professional artist and an advanced amateur photographer.
