Las Hedas! -Spyri

This is a story I wrote for Spanish Class, here is just a quick translation I made last night:

It was a cold December night when the beautiful couple walked in to a bar in Athens. The room was smoky and noisy; people were slowing dancing Michael Buble’s Fever adaptation.  The man was tall with long blonde hair. The lady next to him was breathtaking: she was brunette with big brown eyes that captured every man and woman in the room. The waiter came soon after, and brought them their drinks, hypnotized by the woman‘s look. 
Couples were dancing around the room, and everyone was feeling cheerfully dizzy. The strange couple started dancing too. Their dance was divine. They were sweating across the dance floor emitting some sort of light. As they were dancing faster and faster, their appearance started to change. The man’s hair turned almost white and got shorter, his ears got pointy and his eyes turned light green. The female, while chanting in an unknown language, was changing too. Her hair became red like fire and her eyes were now green too. Her ears were like the male’s.  
The light became stronger and stronger, now they both looked like gods! Their fingers became longer and their teeth turned sharper. Then suddenly, they parted away. Only a scream was heard: "Fairies!" And the couple jumped among the hypnotized people. They were biting them and cutting pieces of them. In a half of hour there was no one alive. The deadly couple was catching its breath. They put their disguise back on and left the massacre scene. 
The next day's Greek newspapers headlines were all about the murder in the small bar.
