 Vampires would actually look like in real life. Forget neck biting. They'd likely have a long, sharp sucking organ like a mosquito to pierce human skin and suck the blood out. They'd have no need to sparkle in the sunlight. But would probably have pale skin if they were nocturnal like many blood-drinking animals. Also, imagine large ears so they can see using sound and a strong heat-sensitive nose to sniff out blood. So vampires would be a little less, frankly, hot, and a little more- AHHHHHHHHHHHHHH
