render this to a realistic quality using material pallets such as concrete wood stone all that any cyan colors should be rendered as a concrete based planters that sit staggered on the main staircase they are made from concrete and shouldnt be blue any red should be a darker staggered stone texture the yellow should be the wooden facade panels the orange is roof underneath a large cantilever add rigid simple lights underneath that illuminate the stairs the dark blue should be rendered as sky do not add objects just render the dark blue color as the sky and sky only the green should be rendered as staggered stone walls in the background render the plaza structure as wood too and add lighting behind it so the plaza space does not look so dark but keep in mind the green stone walls that are behind it
