I will admit, while the biker mustache he had was cool, I think the beard looks even better.
It gives his face more character.
With this new look of his, Kenny reminds me of Kevin Costner when he played Devil Anse Hatfield, on the Hatfield's&McCoy's miniseries.
I figured his hair would be longer, as it's been 2 years or so since the first season.
But hey, he looks good!
