A vertically oriented oil painting on canvas, measuring approximately 1.5 times taller than wide, is depicted leaning against a reddish-brown brick wall. The painting features a head-and-shoulders portrait of a light-skinned male, centrally positioned, gazing directly forward with a subtle smile. He has dark brown, short hair styled upwards, dark brown eyes, and a full, neatly trimmed dark brown beard and mustache. He is depicted wearing a dark, possibly black, outer garment over an olive green inner layer. The background of the portrait is rendered in mottled grey and muted blue tones. A faint signature, "Duung 2018," is visible in the bottom right corner of the painted canvas. The brick wall behind the painting consists of rectangular bricks laid in a stretcher bond pattern with visible mortar lines. The scene is located in Nha Trang, Vietnam.
