I would hope that anyone who watches this could appreciate how well-crafted and high quality everything put into this was. High quality voice acting all across the board. Close up shots create a heavy and oppressive atmosphere that gives character to the locker and small room settings. The artist's great attention to detail in all the subtle animations like the lighting, head tilts, shifts in facial expressions, and hair movement keep everything feeling alive and non-static.
The story itself is more or less an introduction to the premise right now, but I feel that it also instills a sense of curiosity and dread as you wonder what Ruby has gotten herself into and how this could all go terribly wrong. I'm a bit biased towards slow buildups, so even at a lengthy (for a one-person animation job) 7 minutes I just found myself wanting to see more.
All in all, it was very refreshing. Or at least something I don't expect to see from an internet cartoon very often. I hope more things in the same vein as this are encouraged and promoted.
