A balanced composition split into two halves, representing peace and war. On the left, illustrating peace: a calm, serene setting with doves flying against a clear blue sky. The backdrop contains lush green meadows and a pristine river flowing gently. On the right, illustrating war: the atmosphere is drastically different with a tumultuous, fiery landscape. There are silhouettes of soldiers with their weapons in the background, under a sky filled with smoke and distant explosions. Please render this in a realistic style.
