Interesting animation. I could tell it was very heavily influenced by the animations of David Firth.
It's very difficult to get a point across through animation in a minute, so I won't comment on narrative. However, in future I think if you're going for the shorter animation, especially an animation with no dialogue, it should work to your advantage to make any background music or sound effects more dynamic, i.e. changing with the visuals, building tension, etc.
All in all I think you're off to a good start and you'll only improve from here with more exposure to the program.
