In nWoD, flaws still exist, but they don't grant a merit point bonus, you'll have to stick with 7. Also, the merits you used were from VtM, not VtR, which is nWoD vampire. If you wish to apply as a vampire, I still have no problem with that, reference the VtR core back, chapter 2 for character creation.
I'd also like for you to have a background story of some kind. While the flaws and the idea paints its own picture to a degree, it doesn't allow for much story to be told.
