Though it's a rough draft, Dolorosa's entry has the most striking characters. From the start, they don't have that cardboard cut-out feel shared by a lot of fantasy out there. Of the entries, it has the most promise. I'll take sarcastic wit and a bit of swashbuckling over stoic caricatures any day.
The others leave me with a feeling of familiarity - it's all been done and braised, recycled as sandwich meat, and finally reduced to hashed. We've seen it all before - the overcrowded and racially/ethnically diverse party, all of whom happen to get along fine, the labored dialogue and exposition.
Just to play devil's advocate, is this really a good way to choose a person to write a novel based on a product you're still trying to market? This could easily degenerate into a popularity contest in which talent becomes secondary.
