I'm not a painter so I'm definitely not the best person to be talking about these things but, just in case this helps.

In the sphere painting you aren't accounting for the light bounced off of the ball back into the ground plane, which would be especially noticeable in the cast shadow area, you have the gradient for the general occlusion shadow but it should be more defined than that, also since the top plane of the sphere is much brighter than the top plane of the ground I'm assuming they have a different local value(different materials), in that case you should be able to see the contrast between the parts of the sphere that reflect the ground and the ones that reflect the walls.

You should even see a very subtle reflection of the cast shadow on the ball itself

I also assumed there was some extra light coming downwards, from either a sky, secondary ceiling light, or just a ceiling brighter than the table/ground plane

here's kind of a replication done in blender (a lot of things are different, I made the ground a lot more reflective, but hopefully it still makes sense), you can see how the sphere reflects on the ground plane.

ignore that specular in the shadow area, that's from the lightsource reflecting off of the ground

I didn't calculate everythin super correctly, reflections on spheres are a pain, but yeah, maaaaybe this helped ? maybe not.

EDIT, fixed it a tiny bit, but yeah, mine is still very sloppy
