I like your twenties style its something unique that stands out.
Nice animation and good story development. I especially enjoyed the theme of the 20s. That being said, my only suggestion might be to shorten it just a bit and work on making the flow a little easier to understand (i.e. the movie they were watching was done in exactly the same style/framing as the actual story, why was the guy arrested?). Take it all with a grain of salt, though, because if this is your first animation, you're off to an extremely promising start. Keep it up!
