Glowing Eyes
3 point Flaw
You have the stereotypical glowing eyes of vampire legend, which gives you a -1 difficulty on Intimidation rolls when you're dealing with mortals. However, the tradeoffs are many; you are a walking tear in the Masquerade and must constantly disguise your condition (no, contacts don't cut it); the glow impairs your vision and puts you at a +1 difficulty on all sight-based rolls (including the use of ranged weapons); and the radiance emanating from your eye sockets makes it difficulty to hid (+2 difficulty to Stealth rolls) in the dark.
