Gesture Drawing

The figures are very straight. You must be softer and more fluid with the movement of your body. Keep practicing. Don't give up, because practice is the key.

You got the main idea of the line of the form, but the joints are still a bit stiff and seem to need some practice - proportions of the joints within the limbs are a bit shaky but the idea of using circles for them is a good way of getting them where you want them - maybe you're using the pencil too harshly on the paper, if that's something you are able to correct you can get more fluidity on the lines instead of just straight ones.
