Yeah so far what I've seen of his face in the game just looks awful:
The skin needs work, the hair needs a lot of work. They're probably going to change it before the release, but still... and where's all the muscle? The expression doesn't help, even though it was set up specifically for this shot.
Even if they touch it up though, he's never, ever going to look remotely like this:
Even pixelated you can tell this guy is a badass, you can tell he's got muscle. I mean just look at him. The cheeks, jaw, chin, neck, smile.. now look back up at the previous shot. This is nothing personal against Frederick, it's just a fact that his facial structure and body build don't match the character and what it represents, and it's probably going to take away from the gaming experience as a result, just for him and other team members who modelled for main characters to get a little more known..
I mean how would people feel playing Duke Nukem that instead of playing this cool, wise-cracking muscle guy, you were actually playing as the guy in the middle? It just wouldn't be the same.
