keep my main building architecture and materials exactly unchanged replace the background to show a realistic dense athenian inner courtyard akalyptos in the background display the rear facades of typical mediterranean apartment buildings polykatoikies with chaotic balconies white roller shutters vintage metal railings and visible air conditioning units on the walls the background buildings should look lived in and slightly weathered to match the authentic urban fabric of athens use soft daylight that creates realistic shadows between the narrow gaps of the buildings adding depth of field so the background is slightly soft focused
