30 min. figure drawing class critique

recently started doing the 30min. figure drawing class mode sessions for warm ups . i feel like my lines still might be too stiff? any criticism is greatly appreciated!

idk if the image will work so heres a link

thank you!

hello! I think your figures are very nice! I do agree they are a tiny bit stiff so I'd advise really following the line of action and equally adding more "action" to the arms and legs as well. I feel like it'd help further the dynamics of your figure. Hope this kinda helps lol
