Excellent descriptions. The world, and Neron's movements in it, were clear and vivid. There's also a great use of feeling in his success. You might weave the music in a bit tighter. The wind feels like a string symphony to me, so the fast-beat dance music threw me off. You might also tie changes in the songs to different moves, a swelling of drums could make him raise the wind, a crashing of cymbals could bring him down.
Really solid though. I didn't think twice about your dance knowledge, the character was so certain and sure of his victory that the dance was just a footnote in his story.
