Elves don't come from the Feywild; certain elves come from the Feywild.
I think elves look pretty faithful to how they are meant to look in D&D. The only real issue I have currently is that the difference between elves, half-elves, and humans is somewhat nonsensical. Elves are not pre-defined as being diminutive emo boys. There's plenty of lore and artwork for the last 40 years that features elves as being no more or no less masculine or hardy looking than humans. Historically, elves (but not drow) have been taller than humans in the Forgotten Realms, but this appears to have changed somewhat around 4th edition, and they're now considered about the same height.
I do not think they should swap the half-elf models with the elf models, but I do think they need to round out the half-elves a little more. Their ears are too sharp, and their features are a bit too elfy in general. They shouldn't be able to pass at a glance as either human or elf. That's their whole deal. They're outcasts in both societies.
