Well, if you ask me if i like them compared to previous DA games, then i will probably say that they don't look bad.
Now if i like them in general, as we see them in DA, eh, i'm not really thrilled about them to be honest.
Distinctively prettier, is a way to distinguish them as the "fairer race". It might sound shallow, but in almost every fantasy setting out there, that's how Elves are typically. In DA however, i find myself liking the human face structure more. Maybe it's just me.
I'm not sure if i'm coming across 100%, but no, it's not the prettyness itself. It's distinction from humans, which i find small, in DA in general. So i'll just leave it at that.
There is also the chance that when i see them in game, i will notice a great distinction i can't see now. So i'll wait till the final product.
Also like i said, you can make them beautiful if you want.
I know, you can make every character pretty if you want.
