That is one fine beard. Period. And you've outlined it expertly.

The shorter corporate look is great on you, but if you're really curious about the natural look, then just put down the razor and go for it. Or you can do as another has suggested, and let it creep down a bit at a time, shaving about a quarter inch "outside" your current outline and expanding its range while keeping a line. You have all sorts of choices.

But what you have looks great, as is.
