was good for a pilot
i liked the character designs, and except for Lucifer's voice, the voices were okay. needs a little timing work, tho. comedy has a pace to it, and if you don't keep up with the pace, it falls flat. if someone has to walk offscreen, for instance, have them saying something as they go. or have something happening in the forground as they exit the room in the background. don't just show them walking off. another technique would involve starting to show them depart, and then refocusing on the story quickly, using only the sounds of their footsteps to indicate that they've really left the scene.
don't let things happen one at a time in a nice, neat sequence of events. real life isn't like that, and it makes your stories more believeable if things overlap a bit.
