Unless she has raven black hair and violet blue eyes, and he has the fabric of his shirt straining across broad shoulders, we don't know our characters' appearances all that much. But time is better spent on deep POV you say.
Well, yes. I do think deeper POV has brought our characters' internal dialogues to life, but at what expense? Let's take Jane Austen, for example. You knew her characters inside AND out. In genre fiction, all the characters I read look alike in my mind. They are simply in different situations. Now, I'll grant you, on occasion we get a good description of a character, but I'm finding it less often than ever before.
Instead, he will have (and I'm guilty of this, too, so don't think I'm not including myself) a jagged scar through his brow, corded muscles along his neck and shoulders. She will have a perfect bow-shaped mouth. They might both have piercing eyes, lines that fan from their eyes. Well, you get my point.
I think it's time for us to spend a bit more time our characters' externals to equal the time we spend on them internally. I want a character to leap off the pages so well that I could pick them out of a crowd.
But that's just my take...
