Impasto Rapeseed Field Under Summer Sky

Vertical oil painting of a vast [rapeseed flower field] under a brilliant [deep cobalt blue] summer sky. Composition: low horizon around the middle of the canvas; the lower half is filled with dense yellow blossoms and green stems in the foreground, painted with thick impasto brushstrokes and visible palette-knife texture. Detail transitions from defined rounded yellow petal clusters and teal-green stalks in the near foreground to a continuous golden band receding toward the horizon. A faint blue mountain ridge appears on the far right horizon. The sky occupies the upper half, grading from light cyan near the horizon to saturated deep blue at the top with heavy swirling impasto brushwork. Sky details: eight distinct white cloud clusters arranged across the canvas, including broken diagonal clouds, soft cumulus puffs, and low horizontal cloud bands. Style: vivid impressionistic handmade oil painting with rich textural relief, cheerful summer palette of yellow, teal-green, cobalt blue, and white. Constraints: no people, no buildings, no frame, no text, no watermark.
