yiyi_oilland, a sweeping mountain valley in early autumn, a clear river winding through golden meadows toward distant blue mountains, clusters of trees along the riverbank, warm late-afternoon sunlight breaking through layered clouds, balanced panoramic composition, atmospheric depth, richly painted natural forms, visible confident brushwork, harmonious ochre, olive green and muted blue palette, traditional landscape oil painting, unsigned painting, no lettering, no text, no watermark.
