Youd have to make them look completely alien to not look human.

They are not supposed to look super alien, but they supposed to have "lighter" skeleton:
Narrow noses
Narrow chins
Slightly androgynous slim body. Consider that while with 170cm healthy weight for a human is 60kg, for an elf it's 50. And elven fey ancestors had no gender.
And yes, tilted eyes not in human way. A human would still have quite straight brow line, elves supposed to have that tilted too.
