Don't take this the wrong way...
Now... a teaser is supposed to showcase the best of the best, to draw interest and awe toward an upcoming event... but every time I see a teaser, the artist... well... they get lazy :(
I gave your graphics a two because there was hardly any. I gave your style a 3 because A) I probably didn't see enough graphics to give your 'style' its real score, and B) If THIS really IS your style, flashes of random, (I'm sorry if this hurts your feelings) sloppy animation between long pauses of text, it can't possibly deserve better than a 3 -_-;
But your sound.. is amazing. You have found JUST the right voices for this production, and the background fit very, very well too.
sadly, that's about it.
Now, I AM looking forward to seeing your Chronicles of Lost, but...
NOT LIKE THIS.
I'm sorry, but you need to go back and make it better than what you've done here. This just doesn't have enough quality or content to support a story as intrigueing as the one you (BARELY MANAGED TO) hint at us.
Good luck, I hope you'll do better next time,
Happy Flashing.
