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!

Thank you

I don't see any guidelines or forms. maybe if you don't know what to focus on it would help to start with the construction volumes and draw your lines overtop of that

If you can, overlay the drawings over the original photos after your session to compare how close you got to the proportions and where you were off.
