Hello eteng,
I really like how deliberate your line work is - I can see you're experienced in making quick decisions which is necessary in gesture practices.
I think that defining the poses a little bit more could help! Try empahsizing/exaggerating what you think the S curve should be, and that should help better depict what exactly the subject is doing in each of the poses. This might even help with your execution of propotions.
You're doing a great job! I am working on things like capturing the line of action as well. Really impressed with your work.
