Looks like you're developing a classic, natural Riker style beard, so don't worry about the cheeks. You'll be able to wear that style with easy and the cheeks may come in time. No matter what, don't do any shaping before the 13 week period is up. They may surprise you yet!

Now, next time you get food in your beard you can just say you're trying to emulate your son

Cheers!
Tom
