You're getting the gesture. But it looks like you're focusing a lot on the contours or outline. Try to exaggerate elements of the pose, especially the initial gesture line. For example, in the female figure, I would drop a curved line from her right shoulder out to her right hip then back to her left foot. Then drop another s line indicating the front of her right thigh and the back of the calf and out through her right foot. Just an idea. Keep drawing.
