I really like Saville's work too. Her composition and technique are what strike me most. I find similarities in her work to the work of Lucien Freud and Euan Uglow, who I think are both tremendous artists as well.
For a point of reference I've included work by Saville, Uglow, and Freud below:
'Suspension' by Saville
'Curled Nude on a Stool' by Uglow
'Blond Girl on a Bed' by Freud
