Charlie,
an excellent song - the two voices belong together and your tech savvy problem solving is always a great example to others.
Nice arrangement and package.

The bass is a little loud and seems to go out of synch from about 1.20 for almost an half minute. There's a pause at either end of that section as if the bass track was split & slid aat 1.18 long a bit then some snipped off at the end of it lopped off before about the 1.50 mark. There's even little notches in the Soundcloud wave graphic at those points.

Now if it was deliberate then you succeeded in building tension then resolving it but in an unusual way.

Cheers
