  "prompt": "Impressionist oil painting of a wooden rowboat drifting on a quiet river at dawn, rendered with loose impressionist brushstrokes and visible impasto textures. In the midground, a weathered wooden rowboat constructed from dark brown oak planks with visible grain and slight silver-grey wear floats stationary on the surface of the water. The river is a mix of pale grey and reflected lilac, with thick wisps of white mist rising off the water in soft, blurred layers. On the far bank, a dense line of poplar trees stands tall, their leaves depicted in quick vertical strokes of olive green, sage, and deep amber. The sky above is a gradient of soft pink and lilac light, which reflects in the gentle ripples surrounding the boat as horizontal streaks of pastel color. The light is diffused and directional, coming from the far horizon just out of frame, casting long, faint shadows across the water. In the foreground, the water is dark and translucent, showing the distorted reflection of the boat's hull. The background consists of the hazy silhouettes of the poplar trees fading into the pale morning fog. The entire composition uses a vibrant yet muted palette with thick, expressive paint applications that create a sense of movement and atmosphere in the early morning air. mnt_oil"
