This, of course, is the character Mei from My Neighbor Totoro. These computer generated images are not new and date from 2009 (so old!). But they're still fantastic. They were created by ZBrushCentral forum member d8Ds as part of a "hardcore modelling challenge".
Above are various expressions Mei makes in the original animated film. You can see how d8Ds brought them to life in highly expressive, totally adorable 3D digital models.
The character totally works in computer graphics. Here is an array of expressions:
And, yes, that's Mei drunk!
