Yes, do keep writing. Meanwhile, in defense of Mr. Tumnus:
We are conditioned by popular culture to think that it will be attractive and/or impressive characters who do the great deeds which make all the difference. It was in conformity with this attitude that Peter Jackson changed Frodo Baggins from an early-middle-aged hobbit gentleman into the pretty boy Elijah Wood. But being heroic is not defined by being glamorous. Tumnus is important in the story of LWW precisely _because_ he isn't an awesome centaur or a dashing swashbuckler. He is the fantasy-world equivalent of an ordinary fallible man--who, at one crucial moment, chooses right instead of wrong, and so makes a vital difference.
