Skyrim reintroduced really angular faces for the high elves. They also had angular faces in Morrowind. Oblivion was the game that broke this trend.
I'm glad they changed that in Skyrim. I guess I eventually got used to it in Oblivion, but every race but the beast races looked so similar and bland (but somehow off) that I sometimes had trouble telling races apart. Once I figured out the new racial characteristics in Skyrim, they look much more distinct and interesting. Although, the first time I saw a woodelf (courier, I think), my first reaction was "What the heck is wrong with that guy?"
Seems like the Dunmer/Dark Elves look more like Romulans (aside from the skin tone) than the Altmer/High Elves do, now that I think about it. At least, it seems like I've seen a couple of them that actually seem to have that "V" forehead ridge. Could have just been the lighting, though.
