Headshot C&C Please

After watching this video by Peter Hurley:

I practiced my head tilt.

Then I decided to practice my PP, focusing on toning down my images that some people think are too vivid.

Here are my final images. 1 with no added contrast and vibrancy, and 1 with a lesser amount of contrast and vibrancy than I usually use.

Please give your opinions on anything you feel, but especially the PP.

Thanks!
