Not terrible, but you need work.
The problem with this is that I have no idea what has just happened and this teaser gives me no reason to ever watch the real movie. Some of the scenes lasted too long and were dragged on forever. The movie as a whole was completely boring and dumb. I know you can draw well, but make something interesting with it k? You need to add more action and suspence and maybe a hint of what's going on or an introduction to a character. Work on it, and you'll be great one day.
