Recently, I've been wondering if my writing has become imbalanced. Particularly concerning when it comes to describing a conversation between characters. I think I've been overdescribing the physical movements and leaving the dialogue itself rather light in consequence. Here is a example from my current story. "Your key, sir?" He shook his head in amusement at the way she said that, knowing full well how many times he asked her not to. He grinned as he tried a different tactic this time, one that would be completely different from the verbal flailing about she tended to bring out of him. Which was odd considering he usually had his thoughts collected most of the time. He leaned forward over the reception desk, propping up a hand under his chin as he nodded slowly, flipping over his hand resting on the surface and presenting his waiting palm. "If you would, ma'am." I'm just wondering if I'm overdoing it on the physical and environmental descriptions while a conversation is taking place, and would like some help in rectifying any issues.
