Finally got a chance to read all three chapters and I'm really enjoying it so far! Seriously, I would definitely buy this if you managed to get it published. I would love to read more of it if you are willing.
As others have already said, your narrative style is very impressive. It creates just the right amount of sympathy for your character. I also like how you're revealing just enough information to keeps us interested without giving too much away.
Reading this does make me want to go and work on my Vampire story again. My Vampires also age much slower than normal and have a high tolerance for cold temperatures (they evolved in a much colder climate than humans), but mine can spend brief amounts of time in direct sunlight without harm (although when passing as human tend to wear sunblock like you described).
My main problem with writing is that I come up with cool ideas, start them and then get distracted by a different idea and start working on that instead. Naturally, this means I tend to make very little progress on most of my stories. I will go back to work on my Vampire story eventually, and when I do there's a good chance I will completely re-write the beginning.
Best of luck with your writing.
