I like the organisation, and I think myself it's good to group modules by the same manufacturer as well. And for example to put all the filters together. Although it shows we have more filters than we need! Perhaps not enough oscillators. There could be sense in organising the layers in a relatively logical/standard pathway. If you start with sequencers, then have oscillators in the adjacent row so that cable lengths are shorter and paths more obvious. Then perhaps filters, then envelopes, VCAs, mixers, effects. So I like your rows, not sure the rows are in the right order. Although LfOs might want a mixer nearby.
