Judging by your link, what you're going for seems like a first-person, past-tense account of events that transitions into third-person accounts, but never quite closes in on such a deep-point perspective as to show us anyone's thoughts. We're often told of what characters are thinking in the moment, but these descriptions are confided to us in third person, almost as if the narrator is disclosing the details secondhand, but to the best of her recollection (e.g. One after another, she thought back on all the wedding banquets she had prepared for the De Ia Garza family, ever cherishing the illusion that the next wedding would be her own.)
Don't describe Grandmother as "Rhanjo's Mother," tell us who she is to the narrator, or if you want to convey Rhanjo's perspective, tell us who she is to Rhanjo. For instance, "When Rhanjo found his mother, she was in a trance, mumbling to herself while all the neighbors looked on whispered among themselves. He thought of all the times she'd looked after his own children when they were little, tended to them when they were sick. Now he had repaid her by leaving her all alone, in a village full of strangers."
And don't call her "Grandmother;" it's way too formal. If you want to convey that the narrator is an adult, call her Grandma, but the trick here is to convey a personal relationship: Granny, Gram, Grana, Nana, Gram Gram, and Abuela are all much better options than "Grandmother," although "Grandma" feels pretty solid. On the other hand, if you're talking about Rhanjo's experience, tell us who she is to Rhanjo in the way that Rhanjo might tell us if he were here.
Don't tell us about "the villagers," tell us about "the neighbors," unless the people in the village are strangers, in which case, you should talk about this as well. Who left Grandma all by herself? Where was the narrator when this was happening? This style doesn't quite engage in head-hopping, but it often jumps perspective, and when it does the transition should feel smooth and seamless, so that now the context of the relationships between characters changes its focus and the language you use reflects it.
