11 secs - that high sustained 'ping' has a tiny bit of harshness around the 4kHz area?...might be higher?
just thoughts...nothing more...
The descending piano motif (which I love)...I kept wanting it to extend a little bit further down each time and finally explode into a full line?
Also...the underlying harmonies are quite static at the moment and that short sharp piano motif is ripe for some different implied chords underneath it...massive possibilities with such a simple riff!
I'm gonna shut up and more importantly shut the lid on my piano!
