If everyone in the group seems to be agreeing with what you say a little too quickly, take the time to talk to each of them separately. Someone who is afraid to speak out in a group is much more likely to express their opinions in a more personal setting. Do your best to remain unemotional, even if you get some less than desirable feedback. Everything seems to be in the right spot, but you need to take a closer look. Certain balances are off at the moment, but the problem might be too subtle to notice upon first glance.
