The opening of this story reminded me of a film that I saw recently called Winged Migration which is all footage of birds migrating and is full of fantastic camera work.
Returning to your story, I was intrigued by the way your economy of the prose (the sentences very streamlined and to the point, broken up like the narrative in a comic book) contrasts with the very opulent, descriptive language that you sometimes use. It's a strange mix.
I'm aware that there is a plot and I rather like the way it is told and unfolds in between the descriptive passages. As a reader of fiction I've never been that interested in plots - I'm more interested in the images a piece of writing produces and I enjoyed your story on that level. It's a solid piece of work with depth and character and there's a consistancy and even-ness to the writing.
The eternal champion - I'm no great reader of science fiction but is that a Michael Morcock concept?
