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 definition and answer can be both human attributes as well as being singular nouns.
Perhaps there's an association between them I don't understand?

'twirly baton releases' is the wordplay.
'baton releases' anagrams to 'ELABORATENESS'.
However, I'm not sure how this is indicated.

'of' is the link.

Can you help me to learn more?
