A very effective adaptation. I think you took the most atmospheric part out of the piece, and emphasized it by making it a track in itself. This would be a good loop to add to a battle scene in a flash game/movie. Excellent. You should see if you can find other parts of my music that you can make adaptations to, since my tracks are only beginnings and short loops anyway of the kind of music I'm experimenting with making.
Keep it up dude.
