Loose Watercolor and Pen Architectural Sketch

Loose watercolor and pen sketch inside [Location Subject], seen from [Viewpoint] toward [Architectural Focal Point], [Central Feature] at center, [Overhead Architectural Feature] overhead. Ink line drawn first and left visible through every wash - [Architectural Linework] and [Ground Floor Grid] overshooting into blank paper, one long confident arc for [Major Curve]. Wash about 65%, warm below and cool above: [Warm Architectural Palette] on [Lower Architectural Elements], [Cool Palette] over [Upper Architectural Feature] thinning to bare line at the crown. Diagonal light shafts left as reserved white paper, the brightest value. Floor in [Floor Color Wash] with a backrun. Figures in three depth bands, clustered and gapped, never in a row: [Near Figures And Scale], one cropped by the bottom edge; [Mid Figures And Scale] scattered at different distances, [Midground Cluster] clustered at [Focal Point]; [Far Figures And Scale] dissolving into strokes. Different actions each - [Action 1], [Action 2], [Action 3], [Action 4], [Action 5]. Five figures colored: [Color 1], [Color 2], [Color 3], [Color 4], [Color 5]. Signage as abstract patches, no readable letters. Uniform ivory cold-press, no aged edges or vignette. Vertical 3:4.
