It looks like you misunderstood my point. I write that elves are different from humans, albeit with some fantasy clichés. But at the same time, I do not believe that we should reduce all cultural and physiological differences to sharp ears and thin physique. However, if the "fantasy non-human race" needs only tentacles and colonies united by a giant psionic brain, that's your business.
And you misunderstand my point. Elves don't look different from humans to me, for the same reason a caricature drawing of a human might not look like a realistic drawing, but is still recognizable as human all the same.
Well, with that kind of logic, you can define most fantasy races as humans.
