I feel really baffled by some people's (no, wait, by most people's) taste here
I'd pick Emmelie way above everyone else. She reminds me of Lena a little: a girl-next-door type and a lot of natural charm. I love how random and uncoordinated her body language in the NF performance seemed. It just felt so honest and straightforward, just like the smile.
I hope they never teach her how to properly smile xD
Oh, and i like her body type too - petite women are the best!
