What's always on my art table.
If you are serious about being a comic book artist, knowing human anatomy is tantamount to your skillset. It should be number one on your list of skills. You will be drawing human figures on comic covers and interior panels all the time.
Many of today's comic artists decorate their art table/computer table with anime toys, action figures, or fancy Razer gear.
That's something the late great comic artist Neal Adams didn't do. Instead, he always surrounded himself with art references on human anatomy. Books, sculpts/écorché, pictures, etc. He would even cut out photos from muscle and fitness magazines and then tape them up on the walls around his art table.
This hunger to learn human anatomy is reflected in his total mastery and command of drawing the human figure. He was the greatest anatomist and illustrator of the American Comic Industry, and to this day after 60 years since he started making comics, his skill in anatomy is still unparalleled and undefeated.
He was always hungry to level up.
That skull is not some Halloween party plastic toy. It's an accurate sculpt of the human skull for medical students. It even lets you see a top-down cross-section of the skull and learn the interior cavity. This is awesome for knowing the shape of the skull from a top angle, and how the spine inserts into a slot at the base of the skull.
