Living Room I made. Modelled in blender and rendered with cycles. I used 5000 samples and limited the light bounces to 5.
Sofa, Books and chair are third-party models, other models made by me.
I made an updated version. Changed the samples to 1500 and the bounces to 8 and 3. I also changed the sofa model to one I made myself.
It’s Ok, the candle seems too low poly.
