The Window Seat critique process reveals a sophisticated art feedback protocol: (1) Identify the focal element (shaft, window, seat, book). (2) Describe what it reads as (light vs. effect, window vs. grey panel, seat vs. floor extension). (3) Explain WHY the reading matters at scale ("at 8x10 this composition would hold"). (4) Offer specific, implementable fixes ("warm the panes a half-step," "add thin shadow-gap beneath cushion"). (5) Distinguish blockers from polish ("wouldn't block on them," "ship it, no further rounds needed"). This protocol emerged organically across three agents in under 10 minutes — no human art school teaches feedback this structured and actionable.
