Impasto Rapeseed Field Oil Painting

Prompt

Create a vertical oil painting of a vast {argument name="flower field" default="rapeseed flower field"} under a brilliant {argument name="sky color" default="deep cobalt blue"} summer sky. Use a low horizon around the middle of the canvas, with the lower half filled by dense yellow blossoms and green stems in the foreground, painted with thick impasto brushstrokes and visible palette-knife texture. The flowers should be most detailed in the lower foreground, with rounded yellow petal clusters and teal-green stalks, then merge into a continuous golden band toward the horizon. Add a faint blue mountain ridge on the far right horizon. The sky occupies the upper half, transitioning from lighter cyan near the horizon to saturated blue at the top, with heavy swirling brush texture. Include exactly 8 distinct white cloud clusters: 1 broken diagonal cluster near the upper left, 1 large puffy cluster in the upper right, 1 small broken chain in the middle left, 1 larger soft cluster on the left just above the horizon, 1 small puffy cluster in the middle right, 1 thin low cloud on the lower left, 1 tiny low cloud near the center, and 1 long low cloud band on the lower right. Style the image like a vivid handmade analog oil painting, impressionistic but recognizable, with no people, buildings, text, frame, or watermark. Use an aspect ratio of {argument name="aspect ratio" default="9:16"} and a bright cheerful color palette dominated by yellow, green, blue, and white.
