I'm seeing things like fine crumple detail on Diana's one boot, skin indentations from Diana's... strappy leg things, and the wrinkles in Cassie's pants (which aren't the way they would actually hang, but *look* like they are, and offer some motion and dynamism to the piece), and a really good sense of gesture and proportion. Mainline DCU (and Marvel) busts tend toward the stiff and unnatural, usually looking awkwardly posed and plastic with weird head-arm-torso ratios. These are internally consistent, have an organic texture and sense of unity, and, despite Diana's hip-cock and Cassie's butt-pop, actually look like the figures are in positions they might voluntarily have moved themselves into.
