I was thinking the sporadic octaves were the fireworks and the background exchange of notes between the left and right hand would be the night breeze or what not.
Casedesus is at (or past) the very fast end of convention, so if you play it a bit slower than that you'll be fine.Feux d'artifice means fireworks, so try and use that imagery rather than a night breeze.EDIT: I should add that the most important thing here is control, so you can make the contrasts you want, and shape the phrases just right. Speed alone will not impress here.
