Themeless #3

Continuing to work at improving my themeless construction with this 68-word grid; I recently said 20-Across during a conversation with family and decided it would make a good seed.

To those who are frequent solvers and/or constructors of themeless puzzles, I’d welcome comments re: what does and doesn’t work here.

Happy solving.
