Create a 5-second cinematic scene depicting the Kurukshetra War. Focus on Karna, a heroic warrior, standing on a battlefield, holding his bow—gleaming in a striking golden color—drawn tightly, ready to unleash an arrow towards the Pandava army. The atmosphere should be intense and dramatic, with dust swirling around from the chaos of battle. Include details such as the expressions of determination on Karna's face, the vibrant colors of his armor, and the vast expanse of the battlefield filled with warriors. Capture the essence of valor and conflict, emphasizing the moment before he releases the arrow.
