here's some work ive done using Lumion 3D.
the model from sketchup is quite heavy and big but ive manage to complete the rendering in just 1 day.
I'm using the image above as a guide
there's a lot of flaws in this rendering that i have to both cropped and filtered the end result. but in the end i manage to complete it. The key in this modelling is to keep any details visible as much as you can because its one of the way to reach photorealistic results in any rendering
