Open to Critique and Suggestions

It's been a long time since I've done gesture drawing. I feel like I'm confused on which aspect of the study I should focus on, either the line or details. At glance, I feel I've made them stiff and I do not know what to focus on. Any suggestion and critique would be appreciated!
