Craft a captivating vector illustration of the Arosa mountain panorama featuring the Schiesshorn peak at sunrise in winter. Utilize flat design techniques to portray the serene beauty of the snow-covered landscape with no gradients, focusing solely on solid colors and shapes. Infuse the scene with beautiful lights, using lachsorange and mitgreen hues to depict the warmth and vibrancy of the sunrise. Ensure that the composition conveys a sense of tranquility and wonder, with emphasis on clean, bold shapes and sharp contrasts between light and shadow. --ar 16:9
