Vibrant rooster proudly struts in a sunny landscape with floral accents.

Generate a naive folk art portrait on a postage stamp of a rooster standing proudly in the center, facing left, with a bright mustard yellow beak and comb, wearing a bold black cross-hatched vest with mustard yellow accents, standing on a small patch of green grass, surrounded by a cream off-white paper background with a faint stippled texture, a few small blue-grey clouds in the background, and a few delicate floral elements along the perforated serrated edges, the rooster's dot eyes and thin line nose convey a cheerful expression, the bold black outlines of the rooster and the background elements are crisp and defined, the warm mustard yellow and black palette is used throughout, the composition is centered and portrait-oriented, the rooster's wings are spread wide, and a few small geometric decorative borders are subtly integrated into the design.
