Pixie in the Subway: A Watercolor Dream

Watercolor illustration of a tiny pixie with iridescent, translucent wings hovering near a concrete subway pillar inside a busy station. Soft washes of blue, pink, and gold bleed into each other; fluorescent light creates a mix of cool and warm reflections on the tiled walls and damp platform. The pixie glows softly with a halo of tiny sparkles, while the background dissolves into impressionistic silhouettes of commuters and a speeding train streaking by. Use loose, wet-on-wet watercolor brushwork with visible pigment textures; keep the pixie's edges delicate and crisp to contrast with the hazy cityscape. Composition: the pixie near the pillar in the foreground, platform edge in the lower frame, motion blur of the train in the distance, and a dreamy, whimsical urban fantasy mood.
