I enjoy doodling over pantos, and I usually don't draw. Do invest in a dry-erase board and practice muscle memory.
Find some fun pantos, try:
www.urbanelementz.com. I am not affiliated, just love their pantos! They also have a monthly club, which makes it more affordable.
Remember to breathe, relax your shoulders, and bend your knees. Change it up every now and then. Drink some water. Good music-? All good fun!
