why are my figures so stiff but my animal drawings flowy

whenever i draw animals i can find the gestural shapes and flow of the animal. It's very much c curves and tappered strokes. The momment i draw figures i don't know why its so stiff. I can't seem to apply the same way of drawing animals to figures, finding the overall flow, not getting blinded by small shapes, then i end up getting incorrect proportions because of it. No idea what to do any help.

From this small sample, it looks to me like you construct your animals using more circles and your humans with more stick skeletons, but it's pretty hard to tell based on just this!
