Nothing too new or interesting
I understand how important it is to create a character with emotions, likes, dislikes and other background informations, but I felt like watching something that would fit better in a "Extras" section of a submission.
I know that the characters must be really important to the story, but I believe your submission didn't showed enough. In my opinion, a Teaser should complete the sentence "This series is about...".
In example, imagine that you are a fan of a specific movie, and your friend never heard of it before. The first thing you tell him about are the details of the main characters, or the story plot?
Well, hope my english is good enough to understand. And I hope this review is helpful to you. And oh, since you're gonna use voice-acting, could you include an optional subtitles in the series? That would help a lot!
