Hi,
First of all, a link to your patch is much better than a jpeg.

Modules for ambient are usually large modules, so you need a lot more space to begin with.
For example, https://www.modulargrid.net/e/make-noise-mimeophon already consumes 16HP
You should think of another voice for those strings. A clone of MI plaits is very versatile.
I don't know what use you give to the two Distinguishings, I imagine effects. For the type of music you want, a resonator like MI Rings and the Mimeophon that I mentioned before would suit you well. You will need effects with a lot more control than disnting gives you. And to shoot everything some trigger/cv generator like MI Marbles (or clones)

A noise source and some utilities like a sequential switch, mixer/attenuator/attenuverter.
