The Alice Margatroid model is probably the best model I've seen in MMD. Though
IA comes close (but isn't as cute). What's particularly impressive is the physics on her dress, flows really nicely, and never seems to have "pop-through", which is quite noticeable when you compare it to the popular Reimu model that's featured on a lot of older MMDs.
@SaintessHearts:
Sweet magic is by far the best Alice MMD
Speaking of the MMD Cup, does anyone know a good consistent source of info? In particular I'd love to see anything regarding voting, finalists etc. What info there is out there doesn't seem to have permeated into the english speaking internet yet, beyond the occasional video links.
