Vintage Watercolor City Poster

@Create image {argument name="city" default="CITY"} — uppercase English city name
{argument name="subject" default="one hero landmark as the highest point, one secondary structure a step lower, a mid-rise or terrain band beneath, a closing mass of trees or water at the bottom"} — overlapping into ONE silhouette, real geography ignored, everything below it dissolving into bare paper
{argument name="palette" default="MAIN (dark) / ACCENT (saturated) / SUB1 / SUB2 (muted)"} — Four colors only
{CAPTION} — 3–5 word English line, offhand, never explanatory

[STYLE]

Watercolor materiality first: wet-on-wet blooms, dark hard edges where a wash dried, density shifting within a single stroke as the water load changes. Pigment pools at the lower edge of each form; dry-brush passages split and let the cold-press tooth show through.

A thick brush pen lays the main contours first — about 40 strokes, no hatching.

Washes cross those lines 1–3 mm off register; color never doubles as the outline.

Coverage 60 percent — the untouched paper is the brightest value in the image.

Windows are short repeated strokes at uneven intervals, never drawn individually.

Form comes from flat washes and line, never from modeling.

[COLOR]

Four only: {PALETTE}.

Cream off-white paper ground, every color one step down in saturation for a vintage print tone.

Accent covers 8 percent of the frame at most.

[COMPOSITION]

Subject mass in the lower two thirds with clear margins left and right; upper third is unpainted paper for the lettering.

The tallest spire may pierce slightly into it.

Sky and ground stay bare paper.

[TYPOGRAPHY]

Top: "{CITY}" in oversized heavy brush lettering, all caps, spanning nearly the full width, wide letter spacing, dry grain streaking white through the strokes, ends splitting. MAIN color.

Bottom right: "{CAPTION}" small handwritten script, ACCENT color.

Signage is abstract blocks of color — no other legible text.

[NEGATIVE]

photorealistic, 3D, airbrush, gradient shading, cast shadows, reflections, logos, watermarks, border frames, painted sky, gibberish lettering, evenly saturated full coverage, mechanical window grids, thin typography, serif or script display fonts, Aspect ratio 4:5.
