Firstly I used google maps walk through mode just get an idea about the building surrounding and the material of the facade, then I choose the mood my image , aftar that I modeled the building facade and started sketcing where I want my cutouts to be , that’s along with setup basic light to match the Idea in mind, then I started the texturing of the building wich took quite some time , all the texturing where done procedurally except for the brick Cylinder Part becase it was giveing some distortion on the sides and it’s really close to the camera so I unwrapped it, the pavement was done with vray displacment modifier but I had to render the Pavement in two parts becasue I ran out of memory
