Based on my experience in design for many years, I strongly recommend focusing all efforts on re-creating or radically changing the materials table, as the materials and raw materials have not been developed sufficiently, as they determine the quality of the work. The current materials and raw materials look like they are cartoonish or industrial and do not resemble real materials. I believe that the only thing left to develop is the materials and their correct interaction with the rendering and lighting to be more accurate and realistic. With my regards.
