Minimalist Vintage Semi-Truck Nursery Art

Create a premium minimalist nursery wall art illustration of one single friendly vintage semi-truck with a simple rectangular trailer, hand-painted in a soft watercolor and gouache style with subtle pigment variation and delicate watercolor paper texture. The artwork should feel soft, timeless, and consistent with a luxury Scandinavian nursery print collection. The semi-truck should be shown in side profile facing right with rounded child-friendly proportions and simplified details. The cab should be painted in a muted dusty navy blue (#59778D), while the attached trailer should be a soft warm cream (#EEE3CF). The windows should be pale blue-grey (#C8D6DD), the bumper and wheel hubs should be warm neutral grey, and the tires should be textured charcoal rather than pure black. The trailer should be simple and clean with no branding or text. The combined truck and trailer should occupy approximately 40–45% of the canvas width while remaining perfectly centered, leaving generous negative space around the illustration. Background requirements (mandatory): The artwork must have a completely plain solid warm white background (#FAF8F3) with only a subtle watercolor paper texture. There must be absolutely no road, floor, horizon line, scenery, sky, grass, shadows, buildings, props, decorative elements, patterns, frames, borders, or text. The vehicle should appear naturally centered on the page with no cast shadow underneath. This background must remain identical across the entire collection. Negative prompt: no highways, no roads, no shipping yard, no buildings, no landscape, no sky, no scenery, no people, no text, no branding, no company logos, no frame, no border, no decorative elements, no clipart, no vector art, no photorealism, no hard outlines, no thick black lines, no glossy rendering, no cast shadows.
