Movie poster with an African superhero

A movie poster with a superhero who is brave and self-sacrificing. He is a symbol of hope and justice. A wide-angle shot showing the superhero standing over the Johannesburg city. High-angle shot of him standing on top of a Johannesburg skyscraper, looking over the city, with vibrant colours, an warm, soft lighting coming from behind to create a halo effect. The costume should be clean, sleek, with traditional South African patterns integrated into a modern suit design, and the Johannesburg skyline must have a bright sunshine, clear skies, and people in the background looking up in admiration.
