Ok so I've gotten help on the smudging issue and it makes sense how to fix it. But I think my lighting is really messed up or something because I cannot see the white spot (the spot that's supposed to be pure white.)
Today, I tried to make the sphere less smudged-looking, and I tried to make it look shinier to make it seem more ceramic. I also moved the white spot more to the right. I still need to make the dark shadow more curved to give the sphere more of a round look.
