Hey Seasick:
Welcome to the Beard Board. I would regret right away if I shaved my beard. One of the lessons you got from that is that you probably feel yourself as one of those who would be happy bearded.

You don't look like a punk kid to me. Your first two photos look pretty mature. Your third photo still looks great. The mustache is really nice. I can see a nice soul patch. I can see where you think that your chin isn't as thick as other parts, but it doesn't look bad. From your photo, I would be inclined to think that the lighting makes a difference. I personally think it is a pretty sweet looking beard. I don't know that there is much to do to change it. I would keep it growing out, and especially not trim on any part of your soul patch. That may help it fill in more like you want. I do know that we are all our own worst critics. So don't be hard on yourself. Can you send updates? And there is one more thing. It is called the 24 hour rule. If you take a wild notion to do something to your beard, wait 24 hours until you have thought it through. Maybe even ask guys here what they think.

What are your plans for growing? We're here for you. Tom
