Design an impressionistic artwork of Superman standing heroically against a backdrop of a fierce battle. His iconic blue and red costume should be vibrant and eye-catching, with the cape flowing majestically behind him. The background should be a whirlwind of color, depicting explosions and the silhouettes of adversaries, all rendered in bright, vivid tones to create a sense of urgency and action. Use dramatic lighting to highlight Superman's figure, casting shadows that accentuate his strength and resolve. The brushwork should convey movement, making the scene feel alive and dynamic. Emphasize the texture of his costume and the intensity of his expression, capturing the essence of a true hero in the face of adversity.
