Serene Sunset Scape 🌅

Create a digital painting of a tranquil landscape featuring a prominent, gently flowing river flanked by tall, mature pine trees under the glow of a vibrant sunset. Employ a warm color palette dominated by orange and purple hues to evoke a twilight atmosphere, enhanced by soft gradients to blend colors seamlessly. Incorporate subtle details such as a flock of birds silhouettes against the sky, gentle ripples emanating from the river's surface, and hints of underlying foliage near the treelines. Ensure the composition is balanced, portraying a sense of calm and serenity. The overall painting should possess a high level of visual detail, without appearing cluttered, creating a sense of depth and naturalism. The art style should be a blend realistic representation with slight impressionistic elements.
