Render Progression from basic layout to final.

Added procedural Carpet by subdividing the base floor mesh and converting to Hair Emitter, with 4 Different colored curves color different shades of brown and added them to a collection.

The basic layout. A centerpiece model, Natural HDRI lighting and a few PBR shaders.

More models and extra lighting

Changed the HDRI and increased light bounces form 12 to 24 as well and changed the F-stop of camera from 4 to 9.5.

Added more models and clutter, tweaked the bedding with blender's new cloth sculpting brush. Changed wall texture. Tweaked the Normal map and Displacement slightly as well.

Brushed the carpet, increased contrast, added a soft box to ceiling outside camera view to fix lighting issues. Smoothed out the topology of the chair and bedding and a few shading corrections. Increased F-Stop to 12. Rendered at 2500 samples with OptiX Denoising. Some post production compositing and color correction.
