Create a high-resolution digital painting of a majestic mountain landscape at sunrise. The artistic style should be a blend of realism and impressionism, with vibrant colors and detailed textures. Use a medium of digital painting with a focus on soft, sweeping brush strokes. The lighting setup should capture the warm, golden light of the rising sun illuminating the peaks. The background should include towering snow-capped mountains, while the foreground features a tranquil lake reflecting the sunrise. Key focus points are the interplay of light and shadows on the mountains and the serene reflection in the water. Apply HDR effect and color grading to enhance the warm tones, and add a subtle vignette for a more immersive feel.
