What elevates Eurorack effects modules from guitar pedals is the ability have voltage control over many of the parameters, either through hands-on manipulation or by utilizing control voltage generators like LFOs, Sample&Hold, Sequencers etc.
You have Pams New Workout in thhis setup, which can provide up to 8 CV sources, but lacks immediate control due to only having one encoder. But even if you use all of Pams outputs, you still have vastly more CV inputs on your three effects modules that you aren't using. I would drop at least one, if not two of the effects modules and add more CV sources, mixers, maybe a filter and, most importantly, VCAs into this system. One knob per function-type modules will make your effects rack very playable. Also think about mixing several modulation sources together before sending them to the CV input of one of the effects. This is almost mandatory if you want to go beyond what you can do with guitar pedals anyway.
