Hey man it's looking very promising for you! For being only 18 I see a lot of hair in all the right places, I'd recommend carving a neckline like jasjes said, this will give you a more intentional look and will make the higher points of your beard show better. Also, don't fret about the mustache, they often take way longer to grow. My mustache is at 4 months and only really started bulking up more at month 3. Keep going man, take care!
