I need to work on the Chinese Checker board itself, some of the faces didn't come out right when i cut it in blender.
The brick wall came out better than expected, all i did was move the light around and it was perfect. It is a PBR.
The ground is also a PBR. Much harder to make vertical displacement look real.
A nice image! The wall and the ground look great. Good use of PBR textures.
Some notes about the rest: the board looks nice, but it's perfectly reflecting. It's a wooden board touched a lot of time by players' hands, so it should look a bit more worn I guess.
Same for the table. It looks like right out of the factory and coated like a piano. Maybe some scratches and a more broken up reflection with a slightly higher roughness (should be done with the path tracer) might look more natural.
And the orientation of the wood texture on the chairs looks kind of weird. The seats' texture orientation is diagonal, the chair backs' is a mix of diagonal and a very unusual (for wooden strips) orientation 90° against the grain, and the legs have a completely stretched mapping.
