A whimsical and mischievous Grinch dressed in a vibrant red Santa suit with white fur trim, sitting on a snowy mountaintop overlooking a picturesque winter town at dusk. The scene is bathed in a warm and colorful sunset, with soft orange, pink, and purple hues blending into the cool blues of the snow and distant mountains. The Grinch wears a sly, playful grin, surrounded by the serene beauty of the snowy landscape, with twinkling lights from the cozy town below. A perfect mix of festive cheer and playful mischief, rendered in a photorealistic, cinematic style.
