& the link because jpgs are not very helpful:
needs more modulation sources & utilities...
modulation sources because they are what create movement
utilities because they create opportunities for patching...
take a look at my signature, especially the formula and see how you can apply that to your rack... it will exponentially improve it...
I'd add at the very least a quad lfo, a simple matrix mixer (for combining modulation sources), an attenuverter/attenuator/offset module and a quad cascading vca and probably a function generator or envelope generator (with at least 2 channels - so something like maths or zadar)
these will stop your drones being static and boring
there's a very good chance that you won't need the compressor...

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
