Both signs start with the dominant hand at the mouth. For 'good', the hand comes down and rests palm-up on the non-dominant hand. For 'bad', the dominant hand twists as it comes down, ending palm-down on the non-dominant hand.
While the formal dictionary sign uses both hands as described, it is very common in everyday, casual signing to drop the non-dominant hand. You can simply bring your dominant hand from your mouth and flip it downward in the air.
Your hand can lightly touch your lips or chin, but it doesn't have to press hard. Many signers start just a fraction of an inch away from the mouth before moving downward.
