I do find it funny she calls them vampire eyes, especially given her interest in nosebleeds (from her previous cycle).
Like you Fanny, I think the video work was terrific. They really did well overall all four of them, and it was a shame they didn't do one more double elimination and give them all another chance. But, that's Tyra's choice and we have to respect it.
As far as Tyra's book, I haven't read it, though it does sound interesting. I commend her for writing a book, because it is difficult. I don't know though if it'll be the full triology like she's wanting to do though. (This is apparently speculation - I haven't heard confirms that she is doing this as a series of three books).
