Reply To: Hard-Surface Modeling Practice
Nice work! For the lighting I think a sunlamp and a environment texture as world-surface will be fine. In the real picture you can see the sun angle.
Best you start with principled shader for glass and some simple diffuse shader for everything else.
After this first settings you can begin with texture the color imput of the shaders.
For more realism change the diffuse shaders also in principled or you train your skills and use just one of them for everything, controlled with vertexgroups, vertexcolors and a combination of textures with colorRamps.
This is just one idea and not the only solution.
sorry for my bad English, it will improve…I be shure.
For the scene behind the windows you could use a plane and something like this:
… and build the backround later, if it impotant for you.
