On Autumnal Sidewalks Covered in Colorful Fallen Leaves

On autumnal sidewalks covered in colorful fallen leaves that create overlapping elements for depth composition, a single dark olive green tench, notable for its glossy mucus sheen, bright orange iris, and rounded dorsal fin, is captured in a front view shot, illuminated by a warm color temperature with side lighting from the left and gentle fill light, all presented in an aesthetic of sepia tones or rich dark colors.
