That's already a good young man's beard, as we like to put it. If you like the natural and wild style and there are no issues, why not leave it as it is? The other way is styling it into a real Riker and groom it. I think both are possible and you can wear both styles with pride, especially because you also have connectors.

The gentlemen above are right, a big bushy full beard is not on it's way at the moment, but you're very young and you've got plenty of beard growing decades ahead of you.

Keep growing!
