Nice detuned piano here. Or is that just tuning? I'm retarded in terms of that side of music theory at this point.
at 49 I can't quite hear what's going on in that bass and so it's a bit distracting as occasionally I hear rumble and other times I don't.
Castanets (is that what they are) could come down, as could your tubular bells, vinyl noise, and other accents. The main melody or counter melody is in your piano and drives the piece. It's a bit covered up with those accents. For the castanet specifically, or whatever instrument that is, an option with more varied velocities and attacks would be your best option.
Otherwise, fantastic piece. Wish there was a bit less abrupt ending.
Great work. Thanks for coming out to NGADM!
