I definitely like Orin with a beard, but it should be well trimmed and fairly short, like the YJ show or the Brave & The Bold.
The more ragged look is fine if we're doing a story like the one Sejic drew, where Arthur was living in squalor and hiding who he was. He was essentially homeless, so the scraggy beard worked. But when he's in something akin to his usual status quo and wearing the orange scales? Keep that beard civilized!
And speaking of beards, Superman looks infinitely better with one. A well trimmed and groomed one, of course.
Of course, I do have a bias here. My beard is a epic thing of beauty that stops passerby and makes them comment about how incredible (and well groomed!) it is.
