Intérieur de Colonie Spatiale aux Cerisiers

2.5D rendered concept art illustration of the interior of a massive, horizontally tilted cylindrical space colony with a diameter of [6400 meters]. The curved inner wall alternates between sections of modern urban districts, lush green parks where [cherry blossoms are in full bloom with falling petals], and transparent glass window panels framed by metal structures revealing outer space beyond. Low white clouds drift along the interior ground surface. The far end of the cylinder is enclosed by a colossal metal bulkhead, softened and obscured by atmospheric haze and blue aerial perspective. Camera positioned near the central axis, looking slightly downward along the length toward the distant end of the cylinder.
