I could see that perhaps with the women.
The starter face for males always has the nose sticking out in a way that reminds me of an anthropomorphic mouse man. That and I have this image in my head of them rummaging through junkyards looking for scrap and old discarded parts. “Rat people” comes to mind. They are generally weird looking to me (at default) and I can’t think of a real-life group they favor phenotypically. They don’t look like any Irish populations to me. They look like what I’d expect Belters from The Expanse novels would look like.
