Its a pretty cool work!
To be an amateur in this u have really good things, the animation its fluid, the concept, colors and style its very interesting and matches a lot with the music and the theme of the animation i like it!
If i can give u a suggestion maybe it will be 2 things: 1- Watch the proportion, the screen or the way to see it its more rectangular, ur animation its into a square, then the colummns black at the sides are a little problem, and 2- improve a little the audio, the music its really cool but the quality of the audio its a little bad in some parts.
even with that things its a really good job keep working!
