This certainly was a good premise, I like the models (especially mom, cousin too is great, but they all are), although they do look older than what is probably suggested, like mid 20s or something, facial expressions should be made match the interactions, like is someone is reacting to something happily, would be proper to have a happy face then, too, and stuff like that (in some scenes they did and in some scenes they didn't, so a little bit of inconsistency there, but nothing major, that can easily be solved). Story also seem interesting for an amnesia/mystery/conspiracy story, it's a good one thus far
I'll be eagerly waiting for more!
