Personnalisez « Affiche du Festival des bateaux dragon en arc aquarelle »

Generate a visual work with the spirit of an Oriental festival illustration around the specific theme: the composition carries a sense of breathing through large areas of clean white space; the subject should not be centered and filled to the edges, but organized into a strong arc-shaped motion trajectory, like the boundary of a ring swept out in one stroke of a wide brush, with the main imagery advancing along the arc, and figures, objects, or thematic symbols arranged in rhythmic progression, forming a reading path that enters from the edge, flows around the scene, and brings the gaze back to the empty center. The background builds layers by overlaying transparent watercolor and gouache: the outer ring has light semi-transparent wide brush marks, flying-white, washes, and dotted pigment, while the inner ring has denser thematic patterns and fine color dots, keeping irregular hand-painted brushstrokes and paper texture at the edges. Colors are extracted from the theme itself, but must maintain a bright, lively, clear and clean high-brightness system: the light background occupies most of the area, mid-saturation colors lay out the ring-shaped momentum as structural color, and a small amount of highly saturated warm colors or thematic accent colors pop out only at the subject's edges, floral dots, and key nodes, creating a clear color gradation and festive vitality. The subject keeps a flat illustration feel, with simple outlines and refined local details, character proportions with a touch of childlike innocence and narrative, and movements unified in orientation along the arc. If text is added, it should be placed in the white space as a quiet information anchor: small typewriter-style caption text paired with a classic serif title of strong weight contrast, generous letter spacing, restrained hierarchy, not stealing the subject's momentum. The overall texture should feel like a modern hand-painted poster on clean xuan paper or fine-grained canvas — transparent, airy, and ceremonial — avoiding full-page crowding, realistic photographic feel, dirty vintage filters, and murky yellowish colors.
