'sup, good Knightly
It looks like it's done a fairly good job of showing the main characters, and it definitely portrays the genre.
I think the trailer is missing a bit, though.
Films, no matter which way they are packaged, are about conflict. Without conflict (of
any kind), there is nothing. People need a reason to care about the characters, even in trailers.
That's really hard to do when the selected scenes to use have neither dialogue nor action.
From the footage in the trailer, it looks like it was shot pretty well. Several of the actors are coming off great; particularly that long-haired fellow... very expressive. But really... who are they all?
Put some conflict into the trailer.
