As far as I know, there are no errors in this model, other than that the lava sphere should be marbled red/flame yellowish orange. I should point out that LDD's hinge controls are much improved--I can bend the drill arm up and down, and the support mechanism (which was quite hard to connect) in the back moves with it!
Unfortunately, the Hinge Align tool doesn't seem to work for the new Hero Factory joint system yet, and if I try to enter a degree value using my keyboard for some joints, it rejects my value and picks a random one near my value, even if my value falls within a valid range of angles.

EDIT: I should also point out that when rotating certain Hero Factory joints, the angles aren't the usual 18-degree increments, and sometimes other axes are rotated while one axis is rotated.
