Hi Noel!
An interesting idea for a source and you turned it into something completely different. I wouldn't have known if you hadn't mentioned. The result has turned out really well.
About 12 months ago, I had toyed with the idea of using the implied chord progression from the first part of Claire de Lune by Claude Debussy to see if anyone would recognise the source - not for deceit but as an experiment, because the chord movements sound very distinctive. I guess I've ruined the surprise of that idea now, so I will hold off for a while.
Anyway, you saw yours through to fruition with a good result - well done!
Andrew
