Here is my advanced, first I finished the modeling of the mass plane.
For my camera I positioned it to see the facade that I want illuminated.I also chose a wide format to be able to crop my image in post production.
For my light I decompose it into 4, first a hdri (visible to camera) to give a global color. Secondely i place my fstormSun.
i find that the impact of the sun on my scene , it is not satisfying so i add another light behind my scene to simulate a strong sun
And finally I add lights to the inside of my building with warm color
i crop my image for my final composition
