Nothing special here.

I achieved this by compositing render elements together in Photoshop - GI, Lighting, diffuse, reflections, overlayed with wireframes and a little specular for the glass to save time from rendering light rays passing the huge glass facade. Im getting comfortable with rendering actively in compositing programs rather rendering passively by setting all render settings and wait for my render to finish. Doing it actively gives me more ctrl and flexibility over my rendering.

Thanks for viewing!
