Create ONE original finished oil painting for the City after rain website-background collection. This must look unmistakably hand-painted in traditional oil on fine linen: confident visible bristle strokes following form, broken scumbled color in the atmosphere, thin translucent shadow glazes and a few thick impasto light accents. Medium-size gestural marks rather than mechanically repeated tiny texture. Observational urban painting with believable ordinary European stone architecture, coherent receding perspective, roofs, windows and embankments built from simple truthful masses. Restrained slate blue, warm grey, raw umber, muted ivory and small dull amber accents. Wet surfaces have broken irregular reflections, not a polished mirror. Atmospheric distance and edges lost into cool humid air after rain. Quiet, sophisticated and slightly melancholy. The painting itself fills the entire image edge to edge, no photographed canvas, frame, gallery wall or border. Absolutely no photorealism, 3D rendering, game-engine lighting, plastic buildings, artificial bloom, gigantic fantasy skyline, neon, candy colors, HDR, airbrush gradients, watercolor washes or a photo with a painting filter. No readable text, signs, logos, UI, watermark, signature or collage. Negative space must be genuinely painted atmosphere, never a blank panel.

Required aspect ratio: 21:9. Composition: Ultrawide 21:9 low-detail oil painting used as a quiet website section background. A distant low city bank is only a subdued small band at the BOTTOM RIGHT, softened by passing rain. Most of frame is atmospheric slate-blue, silver-grey sky and still river, separated by a subtle low horizon. Barely a few warm ivory horizontal reflection touches near far lower right. Broad purposeful brushwork with subtle linen showing through shadows. Central 70 percent stays low contrast and free of distinct objects for copy, but never flat color or digitally blurred. No bridge or foreground objects.

The supplied image is only a collection style reference for oil technique, muted palette and level of abstraction. Paint a completely new scene with the requested composition and aspect ratio; do not repeat its bridge, towers, railing or skyline.
