Your hairs in the front look strong and will only continue to look great. I believe that you could have a beard. I don't know if that's what you want but I would keep the chinstrap and mustache, then allow the connector hairs fill in. I think I saw an older picture that had enough. Without question though what ever hair you keep on your face is going to look good whether that's a solo stache, just a goatee or a combo. Have a good trip.
