The posterior sideburn edge is arcing away from his ear before coming back to meet the hairline just above the ear. This creates a large blank area between the ear and the beard which serves no purpose and does nothing to accentuate Cowboy's rugged features. I photoshopped a corrected version of Donald's beard so you can see how it should be shaped. You'll notice that despite Conor's hobo beard at least the posterior sideburn edge is aligned with the edge of his ear, as it should be.
I noticed you made his beard black, even though beards have more red/brown in them, so I fixed it. I also noticed Donald was lacking the curly mustache that would really accentuate his manliness, so I added that in as well.
Cowboy doesn't fit your social norms. I mean, haven't you seen how far he trims his beard from his ear? That motherfucker is a loose cannon who must be stopped
