Semi-abstract mixed-media digital artwork, watercolor and ink wash with painterly digital treatment, tall 9:16 vertical composition, matte mid-grey paper background filling the whole canvas. A lone white sailboat with a dark hull sits on the waterline just below the centre, in front of a dark futuristic skyline and an enormous full moon. MOON: a vast cream-white full moon fills the upper left, its surface finely grained and stippled with soft craters, its edge dissolving into drifting white spatter and scattered star specks. A soft warm halo bleeds outward around it. SKYLINE: across the middle, a dense silhouette of dark skyscrapers of many heights, spires and slender antennae at the top. The left towers are cut into translucent panels glowing electric teal and cyan; the right towers fall into near-black, lit by warm amber and orange windows, with glowing orange street lamps and floating light points along the waterfront. CENTRE: the sailboat, small and precise, two pale cream sails catching cool light on one side and soft warm light on the other, a slender mast, a dark hull with a sharp vertical reflection beneath it. Fine white spray and light dust hang around the hull. WATER: below the boat the surface becomes sculpted ripple ribbons spreading in long horizontal waves toward the viewer, built from glossy liquid-ink bands with bright white specular highlights. Left side teal, turquoise and ink-black; right side deeper black with warm amber streaks reflected from the city lights. The ribbons widen and thin downward, the lowest breaking into drips, smears and splatter that fade into the grey background. TEXTURE: ink wash bleeding, granulated pigment, stipple dots, splatter, distressed melting edges where the scene dissolves into neutral grey. High contrast, glossy wet highlights against matte paper, no frame, no border, no text, no signature.
