Alternative Scores - Critics, pls!

[eduardo]

Hello!

I´m studying film scoring and sometimes I get short films from youtube to compose alternative music for them... Almost one year ago I wrote an anternative score for PIXAR´s short film "One Man Band", and I´m posting it over here to get some critics of my work. Please, don´t be shy to point my lacks:

I also wrote alternative scores for many other shorts, but if you wish, I´d like to get your opinion on the score I wrote for ANIMUSIC´s short film called "Heavy Light" (it gave me a hard work on synchronization, cuz actually this animation was originally synched to the MIDI file; and I made the opposite: I synched the music to the animation):

Thank you!

Please, don´t consider the low audio and instrumental quality; I didn´t give too much atention to mixing, orchestral programming and mastering, and by the other hand youtube compress the audio file making it sound even worst...

thanks
