樱花盛开的太空殖民地插画

High-definition, high-resolution 2.5D rendered illustration. A massive, horizontally tilted cylindrical space with a diameter of 6400 meters. The inner wall alternates between sections of green space and urban areas, and sections of glass and frames. The cherry blossoms are in full bloom in the green space, and their petals are falling. Beyond the glass, outer space is visible. White clouds drift along the inner surface of the cylinder. The innermost part of the cylinder is blocked off by a huge metal bulkhead, which is obscured by air. The distant areas appear blue and hazy due to atmospheric perspective. The image is taken from a camera angle slightly looking down toward the end of the cylinder from near its central axis.
