The face is modeled with thick, expressive lines and a palette of greens, pinks, and ochres, suggesting the play of light and shadow across his features. His lips are slightly parted, and his gaze is steady, directed outward with a calm but alert expression. The background is a vivid green, densely patterned with teardrop-shaped motifs and swirling orange lines that wind among stylized white and pink flowers.

The floral elements are painted with short, rhythmic strokes and outlined in orange, echoing the energetic treatment of the beard. The composition places the subject's head and shoulders prominently in the foreground, cropping the figure at the chest so that his presence dominates the canvas. The background pattern does not recede but presses forward, flattening the space and enveloping the sitter in a tapestry-like field of color.

Every part of the surface is animated by visible brushwork, from the undulating lines of the beard to the stippled dots of the green backdrop. His beard is rendered with swirling, multicolored strokes of brown, ochre, and purple, creating a sense of movement and volume. In the upper right corner, pink and white flowers with radiating brushstrokes cluster together, bordered by curling orange lines.

The lower left corner features a large white blossom with green leaves, partly cropped by the edge of the canvas. The green background is densely packed with small, almond-shaped marks in white, systematically arranged to create a textured effect. The edges of the figure’s coat are outlined with deep blue lines, sharply separating the figure from the patterned backdrop. The artist’s distinctive approach is evident in the thick application of paint and the expressive use of color, which together convey both the individuality of the sitter and the artist’s own vision.

The subject’s direct gaze and the decorative, almost abstract background reflect a synthesis of observation and imagination, hallmarks of van Gogh’s portraiture.
