I've just watched the first episode of SheZow, and the animation is pretty good. Not Titmouse (Motorcity) or Augenblick (season 1 of Superjail!) or even Fresh TV (Grojband) good, but certainly far above others. A good variety of character perspectives are used, and particle effects like smoke are nicely done.
And speaking of Titmouse, I've been bombarded with web ads for the new season of China, IL, and it looks darn impressive despite the sketchbook style.
