I believe the answer is:

elaborateness

I'm a little stuck... Click here to teach me more about this clue!

'highly complex nature' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'twirly baton releases' is the wordplay.
'baton releases' can be anagrammed to 'ELABORATENESS'.
But, I'm not sure how this is indicated.

'of' is the link.

Can you help me to learn more?

(Other definitions for elaborateness that I've seen before include "Complication" , "Complicated detail" , "very detailed quality" .)
