Create a serene and elegant illustration of a mountain lake scene with vibrant autumn foliage, using a minimalistic and flat vector style with clean, sharp lines. The composition will follow the rule of thirds, with the lake sitting in the foreground, occupying one-third of the frame. The forested area will extend to the mountain base, with each tree depicted in warm, golden hues and clear shapes, contrasting against the cool tones of the mountain and water. The snow-covered peaks will rise gracefully in the background, outlined with crisp, pale shades, creating a visual balance between warm autumn hues and cool, wintry tones. The camera will be positioned at a slightly elevated angle, with a wide-angle lens (around 24mm) to capture the vastness of the landscape. The lighting will be soft and warm, with the sun positioned at a 45-degree angle to the left, casting a gentle glow on the scene. The shutter speed will be set to 1/125s to freeze the still water and capture the serene atmosphere. The color palette will feature a rich but controlled combination of warm autumnal colors, including burnt orange (#FF9900), golden yellow (#F2C464), and deep red (#8B0A1A), balanced with soft blues (#4567b7) and creamy whites (#FFFFFF) to create a harmonious and striking effect. The colors will be applied in a layered, gradient style to enhance the sense of depth and dimensionality. The illustration will have a subtle texture to give it a organic feel, with clean lines and simple shapes to maintain a minimalist aesthetic. The overall mood of the image will be peaceful and calming, inviting the viewer to step into the serene atmosphere of the mountain lake scene.
