improval 

improval is a type of review that focuses on proposing improvements rather than determining approval or disapproval

I always run drafts of my professional writing past my wife, a college professor, for her improval, although I reserve the right to reject her improvements.

improvable 

A place or thing which can be improved, a person who is capable of improving themselves or is willing to listen to someone who wants to show them how to improve.

Eddie is not improvable, he doesn't even answer his Father's telephone calls or emails because he does not want to listen to his Father's advice. It seems he thinks he knows better.
