Here is the scene without the Car This is directly from Blender! I just have some more minor tweakings and perform another render with the car in I have also just noticed that I had forgotten to apply the mirror mod on the balcony (middle building/ mirrored texture)
I might not use DOF on that but instead play with the colors and contrast instead to create the focal!
Someone suggested me to create some motives with the stones in the floor to make it less monotone and I have just started that
I hope you like so far
