Rape Culture Centerpiece

I really want my centerpiece to be a conversation piece on rape culture. I'm planning on creating a vase that's the form of a woman's torso. I want it to be a provocative piece so that's is almost uncomfortable to look at so it creates a conversation. I'm struggling to make the form look less like a mannequin without abstracting it down, too much because I still want it to be very representational. Also, I've never drawn a figure previous to this so I keep having trouble with proportions and trying to figure out the actual construction of this form. Here's the pictures of my sketches. I'm still researching more and more on human forms. Two people I'm specifically looking at are Mary Frank and Akio Takamori. I'm also researching contrapposto sculpture because Roman sculpture is very dynamic and I think the reason my sketches look so much like a mannequin is because of the perfect symmetry and lack of movement.

This is a piece by Aki Takamori that is all slab work.
