In a captivating digital illustration that beckons the serene melancholy and mystery of a setting sun, a river gently flows through an endless swamp set against a pale green sky, merging seamlessly into the distant mountains. This enchanting scene is punctuated by the warmth of a large orange sun hanging low, casting a gentle light over the forest and the dark, scattered rocks that dot the landscape. This artwork combines elements reminiscent of Japanese animation with the lo-fi, minimalist styles of artists like Jon Klassen, Atey Ghailan, and Kentaro Miura. The muted greens and browns, alongside soft tones and delicate brushstrokes, enhance the somber atmosphere, creating a sense of tranquility and calmness. The use of low-saturation colors, a flat illustration approach, and a soft glow effect further emphasizes the AI art style customization using –sref, showcasing a skillful blend of artistic influences that perfectly captures the essence of a quiet, peaceful environment.
