If you write about Elves in the way Tolkien 'saw' them then yes you would be compared to him. And loads of fantasy literature alas does have Elves similar to his. 'Alas' because they get on my nerves a bit when they are too priggish. Oh the blasphemy! Sorry, I just wish he'd made them a bit
nastier. This is why I like Galadriel, Eol and Feanor.
Other writers never seem to throw a few more ambiguous and interestingly flawed Elves into the mix.
If you want to see a really interesting interpretation of Faerie try Susanna Clarke's Jonathan Strange and Mr Norrell - you'll find some properly
frightening Faeries there. Or Neil Gaiman's Stardust - but make sure to buy the Charles Vess illustrated version.
