I see some potential here
Definately sounds like you're pretty new at audio, but I can hear some potential in this.
First and foremost, you need to increase the master volume of the song. Campare your song in your program to a song playing in an audio player to find a good volume setting. Having too low of a volume is a hassle and also can cause some quality to be lost.
I like your score behind this, while the instruments are nothing special, I can see something pretty nice created with the score you have here once you get a little more comfortable with your program.
Keep at it, I'll keep an eye out for your stuff in the near future :)
