A little tip...
DON'T USE HIGH PITCH SOUNDS WHEN YOU SAY TO PUT ON THE HEADPHONES >:(
It raped my ears.. T-T
The animation was average...you could make the music sound softer, also you could had a more catchy sound rather than 8-bit cellphone sounds raping ears.
Also the music with the animation sync could have been better.
Try improving those aspects and maybe you will get something smoother
