Your gesture drawings are all really nice, and have a lot of movement in them and really express the pose and movement.
In some of your gestures some of the joints and limbs feel a little awkward. It might be worth running a separate line of action through the direction the limbs are going to more emphasize the movement and not break the solid dynamics you otherwise have.
My feedback might not be 100% correct though so hopefully someone else can give feedback too ^-^
