Historically, elves look like all sorts of variations of the human form, mixed with human features. Tolkien's elves were just stretched out a bit but folks who saw the early Hobbit and LOTR animated films in the 70's recall how different they looked from modern super-aryan elves of film. From the early 20th and late 19th centuries they looked more like what we think of as goblins, or tiny children with odd animal features. Basically, an elf can look like whatever you want it to look like, it's all fair game, since it's all folktales, and the DnD art I've seen runs the gamut from traditional folk art to just people with pointy ears. This is a pointless thread IMO. [url=https://nt.global.ssl.fastly.net/images/1431823201067-rackhamheaderimage.jpg?width=1920&auto=webp&crop=16:7]rackham elf[/url
Also, true, but these are Realms (D&D) elves we are talking about, and they have been very thoroughly described and illustrated for abour 30 years now, and one of the biggest reasons why they don't just look "like beautiful humans" is, that they are literally alien to Abeir Toril... like dwarves, they have no genetic ancestry with the planet's native humans, hence why they only vaguely resemble them, at most.
Contrary to, for instance, LotR, where the ancient Elves basically originated all intelligent live... even Orks and Goblins.
