Hello, I have read your description, and would like to submit an application. I am 14 years old, and I live in Australia. I have a vast understanding of music, and play multiple instruments myself. I am a lover and composer of film music, and I would enjoy getting my work out there. I would not be asking for any pay whatsoever, just (as you say) something to go in my portfolio. If you supply your email address, I will be sure to send you a sample of my music. Look forward to finding out more about this short film, it sounds great.
