深いブルーとゴールドの表現的なうねりイラスト

A bold, expressive illustration in a post-impressionist, Van Gogh–inspired style, featuring dynamic swirling brush strokes, thick textured linework, and strong directional movement. High contrast colors with dominant deep blues and warm golden yellows, giving a rhythmic, emotional, and energetic feel. Hand-carved woodcut or engraved illustration texture combined with painterly strokes, dramatic lighting, rich shadows, and a slightly vintage fine-art poster aesthetic. Highly detailed, artistic, and expressive.
