분홍색과 흰색 구름 아래, 푸른 언덕 위에 우뚝 선 픽셀 아트 나무

Create a pixel art image of a serene landscape with a single Huge leafy tree atop a green hill. Use vibrant green shades for the rolling grassy fields, forming soft organic terrain. The sky should feature a gradient from deep blue at the top to pink and purple near the horizon. Include a dramatic, voluminous cloud in pink and white, suggesting sunrise or sunset. The tree should be a dark silhouette contrasting with the vibrant sky, acting as the focal point. Use a limited color palette typical of pixel art, with dithering for smooth transitions. Emphasize tranquility through careful color choices and pixel-perfect details.
