Depending on your opinion of beauty, making a beautiful female Dunmer in this game can be next to impossible. I'm glad that the Mer have more distinct faces now, but sometimes they are a bit too alien looking.
I wish the first thing I had said as a child was, "Qoute". That way when I die, I could say, "Unqoute".
If by good looking, you mean sexually appealing, well then Argonians and Khajit would be impossible.
But you don't have to be sexually attracted to something to see the beauty of it, the way a swan is beautiful. Pretty easy to make a pretty looking female khajit, what with all the accessories and color schemes. Argonians you can customize the frills so they look like a peacock dinosaur with bright colors.
