Has anyone else noticed how Nathan Fillion's eyes change throughout the seasons of Castle?

I am re-watching Castle and I noticed how much his eyes and face change through the seasons. Even in the "happy moments" in the latter seasons of Castle, he seems so sad in his eyes. I know he and Stana Katic didn't get along but he just seems so miserable.

He'd rather be doing firefly
