Man, that’s hard. Really, I kept digging in my mind but nothing. So I’ll just throw a few ideas at you, see if you’ll grow to like any though I do know they’re not that much alike, but some features they do share with the following: Jared Leto, Jackson Rathbone, Paul Walker, Matthew Davis, Luke Mitchell aaaaand (you gonna laugh) David Beckham. Only that, Louis has really unique face, his chin is narrow, eyes are narrow and relatively small and the effect alltogether looks good though it’s very hard to find because most men has wide jaws suchs as Paul Wesley, Josh Hutcherson, Shane West, etc. Even Bubbles kept thinking about your question but this is the best we could come up with.
