Create a top-down concept sketch of a vibrant, futuristic 3-lane MOBA map called 'Graffiti War.' The map features three distinct lanes resembling urban streets and alleyways, each with unique themes: a neon-lit downtown street, a gritty industrial alley, and a colorful arts district with large graffiti murals. Include vertical elements such as rooftop pathways and pedestrian bridges connecting lanes. Between lanes, show an intricate jungle area designed as underground graffiti tunnels and abandoned art studios with multiple entrances and exits. Place 'paint monster nests' near jungle entrances, appearing as glowing graffiti spots. Highlight interactive paint zones in each lane—small patches of ground glowing in team colors that grant temporary buffs. The bases are large digital billboards or mural walls at opposite corners of the map. Add environmental details like malfunctioning neon signs and steam vents for hazards. The overall art style is cartoon-like, bright, and energetic, inspired by Fortnite, Splatoon, and Valorant." See more
