draw with your shoulder not your wrist.



Use big sweeping movements.



And make a lot of bad drawings, thousand of bad drawings.



Go to Quick pose dot com or something to find gesture drawing, draw fast, dont care if you make mistakes. Get some copy paper for super cheap and draw 30 second drawings. Then throw them away. Dont make art just practice making art. When you care about it as a "finished" piece you might over think stuff. If you know that no matter how shitty your drawing is you will throw it away in 30 seconds and have another chance. When you practice like this you just really start to experiment . Keep at it draw alot and you will figure it out.
