Coppia a spasso in un prato piovoso con arcobaleno

A vertical romantic impressionist oil painting of a young couple seen from behind, holding hands and walking through a lush flower meadow in the rain toward a warm glowing sunset. The man wears [a light blue rolled-sleeve shirt and dark pants]; the woman wears [a flowing teal sleeveless dress with windblown long dark hair]. A large, vivid rainbow arcs diagonally across the upper sky from left to right, framed by stormy gray-blue clouds breaking with golden sunlight. The foreground and bottom half feature dense green foliage and chunky knife strokes of [yellow, cream, and orange wildflowers]. Visible elongated white and pale-blue rain streaks fall vertically across the canvas with glossy droplets. Painted in heavy impasto palette-knife technique with textured ridges, vibrant saturated colors, and expressive brushwork. Backlit centered composition, no text, no borders.
