Well...I firmly place my vote on "no".
I found, when I read the book, to initially imagine the elves with pointed ears, due to my upbringing of such.
However, when I developed actual thoughts and pholosophies on these sorts of things, I found that I prefered to think of the difference between elves and humans as more intrinsic, rather than simply a physical difference.
Of course, this could get messily C v.s. R , so those are my two small cents.
