While 3D comics can be a pain in the arse, losing the dynamism of the artist's line in the fuzziness of a faked new dimension, the thing I always dig most about these comics isn't the actual art, no matter how thrusting it is. It's the way the speech bubbles work.
They're just hanging there in space, on an whole other level from the penciled and painted art. The stark whiteness of the bubble giving even more depth as the action takes place on a bulging paper tableau behind them. Bubbles and captions are always floating in space, but they float higher in 3D.
