Big change is the entire figure is designed around using Joint-Controled-Morphs to make mor natural operation, I think (talking as a customer) DAZ did a superb job. They also redid a lot of the morphs, I think, and while they have the same names as the old they work in a more realistic manner. The hi-poly count is nice, but it is really a means to the end, nota big plus in itself, some very high poly count models neither pose or render any better than Vickie. Let me suggest she isn't perfect, but she is a major, major improvement. Let me also suggest that some of the "bad" renders you see either weren't posed correctly (her joints have to be operted in a different manner for best results) or are the V3/V2 version. The downside, of course, is she needs a whole new wardrobe. And let me say, as I finish up the "Glamorous Vickie" set (based on V3) that properly operating clothing is tougher to make (or rather fit). Some clothing makers might not be up to the task! ;-)
