Minimalist Vintage Garbage Truck Art

Create a premium minimalist nursery wall art illustration of one single vintage rear-loading garbage truck, illustrated in a hand-painted watercolor and gouache style with soft blended colors and visible paper texture. The truck should be shown in side profile facing right. The body should be a muted sage green (#A8B18F), while the cab is a warm concrete grey (#B7B2A7). The rear collection section should be simplified and softly rounded rather than mechanical. Tires should be textured charcoal grey with warm grey hubs. Keep the proportions soft and child-friendly. The truck should occupy about 35–40% of the width with generous surrounding negative space. Background requirements (mandatory): Use a completely plain warm white background (#FAF8F3) with only a faint watercolor paper grain. Absolutely no ground line, floor, road, landscape, scenery, sky, decorative objects, shadows, text, or patterns. Negative prompt: no roads, no bins, no rubbish, no city scene, no landscape, no sky, no people, no buildings, no hard outlines, no vector art, no clipart, no realism, no frame, no border.
