The audience reactions are based entirely on how engaging your delivery is. The audience will nod their heads if you have good pitch, pace, and volume variability. If you are monotonous and boring, they will look away, talk to each other, and act distracted. In PitchVantage, just as in real life, you need to pick up on audience cues to keep their attention. Your goal in PitchVantage is to get as many head nods as possible.
