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 horizontal painting. A quiet wet stone promenade and low row of old riverside buildings concentrated on the far RIGHT third. A single warm streetlamp, loosely painted tree branches at the far right edge. The LEFT two thirds are soft slate-blue river, rainy air and sky with gentle brush variations, kept low-contrast for a heading. Long horizontal river gestures and one small ochre reflection near the right edge. Camera eye level, believable scale, coherent simple architecture.

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.
