I say give it a couple or three months. I think you have what it takes for a decent beard, especially for 22. We can't all be Burke Kenny now can we?. Your stache, chin, neck, and jawline already have good coverage. Don't try and define a neck or cheeck line for at least 2 or 3 months, it's going to look a little sloppy for that time but you will thank yourself for it later. Come here for tips and support and you will be fine
