Create an image that juxtaposes the delicate beauty of nature with the harsh reality of urban decay. Show a vibrant cherry blossom tree in full bloom growing out of a cracked concrete sidewalk in a dilapidated city alley. The tree should be the focal point, with its pink petals contrasting against the gray, graffiti- covered walls of surrounding buildings. Include a small bird perched on one of the branches to emphasize the theme of resilience. Highest- Quality, 4k, intricate details, visually stunning, Masterpiece
