Hands aren't hard to draw because hands are super complicated; hands are hard to draw because humans are evolutionarily finely tuned to recognize and be disgusted by distorted human bodies, which in nature is a signal of disease. Look at the diversity of broccoli proportion at the grocery, then imagine hands with the same diversity -- grotesquely long or lumpy or twisted, which too few or too many fingers. OTOH, cartoon hands, outside the uncanny valley, look fine, even when (as is common) missing a finger.
