First, in reference to your other post, I think you will discover why so many people stick with the bigger/more popular names in the modular community... because they are available. Many of the modules you have chosen here are discontinued (Cjwemann, ZVex, Error Instruments, Folktek) and will be very hard to source. Even if you find them on the used market, you will likely pay a $$$ premium versus something that is readily available and will perform a similar task. Sure, the cheaper or more plentiful modules in production may not have the same niche or "cool" factor, but the point is the music, not the name on the faceplate.
I'll take a look at your arrangement and look for missing utilities etc. later today. Some of the other folks here will probably have some common beginner guidance on that.
Have fun and good luck!
