I'll give you my opinion if you allow it; I am a musician with many years of experience, 41 years to be exact; I consider that you should give more volume to the voice and lower it a bit to the musical background, I also do not understand why in the end it is without sound, you should add some effect; For the rest, I really like the visual effects.
By the way, I discully my English, is that I speak little and use the translator.
I send you my greetings
