I know, it's not really a rule but still...
I like the idea of a demonesque appearance, but when I picture a Tiefling, I don't picture him with the large brutish horns that you see in the PHB excerpts we've found. I think of Tieflings as cunning, mischievous and sly - not hulking or brutish. I imagine a visage of something resembling the popular conception of Lucifer.
They can keep the tail though. That's cool.
