So this is another test just with different shapes.

The first image the cube she is sitting on is using the standard GlassBsdf straight up, which gives some hard reflections.

This one it uses my material, which give some more soft reflections.

I also looked up some references for glass spheres and think it does pretty well, I think my glass is very clear compared to those in the image and also not sure how much photoshop went into these, but overall I think it does well, if some roughness is added, a more intensive light is shot on them from the back.
