Keep in mind that the number of submissions we usually end up with in competitions such as this is always greatly lower than the number of people who signed up to compose.
That being said, here's some suggestions for judging criteria: Judge each piece upon these topics, all with a grade (1-10), and a comment: Selection and appropriate treatment of text, Substance of musical ideas (themes, motives, development, etc.), Harmonic control (accessible yet interesting and flowing harmonies), Idiomatic and appropriate accompaniment (if applicable), Freshness/originality, Notational clarity, and Sensitive vocal writing (ranges, tessituras, difficulties, etc.).
I got those topics from an existing Song Cycle competition, but they apply here just as well.
