Batman in the rain by the city

A rainy, dark sky background with Gotham City and Batman flying in the air, wearing his iconic costume and cape. The details of Batman should include a muscular physique, with a stern and determined expression on his face. His eyes should be intense and his jawline sharp. The rain should be depicted with droplets falling from the sky, creating a moody atmosphere. The cityscape of Gotham should be filled with tall buildings, dimly lit with neon signs and flickering streetlights. The colors should be muted and desaturated, giving a somber and mysterious feel. The lighting should be dramatic, with shadows cast by the buildings and illuminated by flashes of lightning in the sky. The overall image quality should be of the highest caliber, with ultra-detailed rendering and sharp focus on Batman and the cityscape. The art style should be a combination of concept art and realistic, giving a gritty and immersive feel. The color tones should lean towards cool blues and grays, enhancing the dark and gloomy atmosphere.
