I disagree. I play a Half elf and they look pretty damn human-esque. The pure elves are easy to tell apart as all their features are more elongated. Half-elves practically look human with slight elven angularity, ears and eyes. The half elves don't all look alike either, that's just one preset, and you chose literally the youngest looking preset of them all for the arguement.
I was lazy to take a screenshot of all the faces. While it is true that I picked the youngest looking one, I still think that all of the half elven heads are better than all of the elven heads. More delicate and attractive.
You are right that half elves look pretty damn human-esque though. The point here is that... So do full blooded elves, actually.
