ModularGrid Rack

I've spent the last few months planning/researching/studying and finally feel good about these modules.

I ended up throwing some utility modules into a smaller, additional rack.

I'm wondering:
- am I missing anything crucial?
- should I scrap the additional rack and add more utility modules to the main one?

General feedback is more than welcome. I still feel like I have no idea what I'm doing.
The kind of music I'd like to make ranges from drone/noise to rhythmic/spacey/electronically-orchestral.

Thanks for taking the time to read all of this.
