Here's a comparison, front camera. From left to right, Vickie 2, Posette, Posette scaled to about Vickie's height and the real April Hunter. It's obvious that Vickie 2's head is a bit smaller in comparison both to Posette and a real woman. April Hunter maps to a scaled-up Posette pretty closely, given the pose she has in the photo, and noting that April is a tad wider because of working out than an average model of that height would be (she's 5'9") and the implants that distort the natural position of her breasts.
