Is mixing post production?

The term ' Audio post production ' is sometimes used to refer to parts of the process of producing music (i.e. Mixing or Mastering), although the standard nomenclature of the Audio Engineering Community refers to these generally as Music Production and any audio produced for moving picture as Audio Post Production.

Explanation:

well seeing i am an artist and i actually did a self portrait; i will describe how i painted it.   i used acrylic on a stretch canvas about 4 feet wide by 6 feet tall. i painted myself smiling in a soft pink long dress, white tile floor sitting on a white couch with a table behind and a vase of gorgeous flowers.   i also had a round white hat with a soft pink ribbon through it laying on the floor and on the table behind me was a lit candle. i kept it simple but soft and romantic.
