Hey, Tom. Great update, and one thing very, very interesting about your beard is how bulky it is in the jawline. Everything looks so great and unique. Your beard will develop even more. If you browse a little bit throught board you'll find a lotof guys whose beards improved a lot in their 40's and 50's so it's not everything lost. As for the different styles, aside from the ones you mentioned, check out hollywoodian beard. I wouldn't shave if I were you, though. HAndlebar looks great.
