<https://s.mj.run/-6Q5ZO8v5HM> Create an illustrative collage that encapsulates the rich tapestry of Sudan's cultural, ethnic, and racial diversity within an urban context, influenced by the historical layers of Khartoum's cityscape. The artwork should intertwine Ottoman-style Islamic architecture, the narrow alleys, and the colorful textiles of African ethnic groups, showcasing the city as a symbol of Sudan’s cultural mosaic. Integrate subtle elements that reflect the social and spatial segregation stemming from historical urban planning, juxtaposed with imagery suggesting avenues for celebrating multiculturalism and diversity. The image should also hint at the need for inclusive urban planning that manages diversity and fosters social equity, hinting at the challenges of managing urban growth and addressing ethnic and racial divisions. The atmosphere should be one of complexity and contemplation, capturing the spirit of a city that stands at the crossroads of tradition and modernity, conflict and peace, segregation and integration.  --ar 3:2 --s 750
