While "you look good" and "you're looking good" are very near equivalent, perhaps "you're looking good" could be used to mark a more momentary awareness that it's looking better than usual or in the past. "You're looking good" could be used more so to emphasize that the attention has been grabbed of the person saying it.

I think "You look good" is more emphatic and direct, but that's about the only difference.
