I don't think A-towa's skin colour is really representative of his race though, or
even accurate for how he is really meant to be, given the fact he has actually been dead for centuries, and is now just a spirit inhabiting the WHM Soul Crystal.
I presume the more pointy ears are just another change that occurs to them when they become padjal though (as horns also grow from their heads it's not too big a stretch to think that their ears could become more pointy too for that matter.
). Remember that Ferne himself stated that only hyur become padjal and not elezen, so yeah, the pointy ears are not proof of elezen ancestry.
