I relate to the message that you're aiming to express in this short.
I say so because I am a musician, yet I have suffered, and am still suffering from the abuse and discrimination my parents and other people around me gave me, particularly in order to discourage me from my calling.
The animation is a product of its time, and it is quite alright. Piano playing in some parts seems a bit unnatural -- the body is often rigid while playing, rather than fluid (as it should be).
The music is where I have to gash points, I'm afraid. It felt a tad uninspiring, and for something along the scale of a person's life story and mission, I always look for the spectacular. This wasn't. To me it gave the feel of something off a soap opera.
My mission is to inspire -- thoroughly inspire. Even with all the limitations I have, I yearn to capture hearts. The animation certainly did set out to do this, despite its few limitations. The music, I know it's no Meat Loaf or Enya or Howard Shore. However, it could still do with a lot more grandeur -- and this really threw off the balance for me.
