Not Bad...But Not Great
The art and animation are pretty top-notch, but there is a huge lacking in the substance department. All we get is a dying girl for no reason, a mention of "unique powers", and an abrupt ending. The poor .gifs didn't help it either. I would've liked to see and know more dealing with these characters. They are the reason for making the Flash, mind you. Without story and substance, there is just filling. I don't mean to be harsh or mean, but I would like to see someone with your talent to churn out much better quality animations, rather than plot-less mediocrity.
