Howdy!
One quick thing on posting racks in this forum: it's really helpful to post a link to the rack rather than an image as it can sometimes be hard to tell which modules are included, and a link lets us dive into unfamiliar modules to see what they do. That said, I took the liberty of rearranging your modules a bit and here's the link:
For arrangement, I'm a big proponent of the ARP 2600 school, with external input and audio sources in the upper left moving through to filters and effects, envelopes accessible to top and bottom, and other utilities and modulation on the bottom. I put the DFAM on the bottom as well for access to the sequencer, and the midi interface on an outside edge for ease of connectivity without crossing over other modules. You'll always have some amount of patch cable spaghetti (which is part of the fun!) but I think this configuration would tame it down a little.
I think this is a good set of modules to start with, but would definitely recommend some more utility modules. Particularly a cascading VCA/mixer like Mutable Veils or Intellijel Quad VCA. More ways to mix audio to send to your effects are always welcome, and they can also be used to mix and control CV to make more interesting modulation. I would also recommend something like the Disting or Ornament and Crime as they have many modes allowing them to act like a bunch of different types of modules. If you find you're using them for a particular function, that can help you decide if you want to get a module dedicated to that function to then free up the multimode module to try something new. Lastly, a dedicated filter or two can be really helpful in sculpting your sounds. I know you have the filters in the Behringer voice module and the DFAM, but putting your whole mix through a filter is fun. Cheers friend, and welcome to the modular journey!
