Flat vector style abstract mountain landscape illustration, 16:9 horizontal format. The distant view features layered geometric triangular mountain peaks in varying shades of teal, some semi-transparent to create a sense of depth. A soft light orange perfect circle sun sits in the upper right sky, surrounded by a faint same-color halo. The upper half of the image is a pale gray-green gradient sky. A semi-transparent white circular mist band stretches horizontally across the mid-section. At the very bottom, dark ink-green triangular foreground hills frame both sides, with a light gray-green curved flat area in the center marked by three parallel thin light white horizontal lines. The whole image uses fully flat coloring without gradient shading, with soft low-saturation colors, clean smooth lines, and no extra decorative textures.
