Good luck with that. Antonia's topology isn't much different than LF's in that area. Quad grid. Tough to do unless subdivided quite a bit, which introduces it's own set of peculiarities for expressions. Generally you'd want to create expressions at the lowest subdivision level possible as it's easier to get the muscular sort of pull of adjoining topology when you move a section. If that makes sense. There's more of a sculpted in place rather than free movement sort of thing the higher you go.
