Not very good.
I'm sorry to say this, but you've done a pretty poor job. It just missed the mark in too many ways.
Let's start with the good: It's pretty recognizable, there's no discord, the drum line is more or less correct rhythmically speaking.
It needs work in a lot of places though.
1. Your drums are too loud. Drums are never meant to be melody and shouldn't be the main track of most genres of music. Scale them back 30-50% and you'll have a more reasonable track for it.
2. Your lead instrument(trumpet? sax?, can't tell through the drums) doesn't have the range it should. The high notes should be higher and part of a richer chord to bring out the dramatic effect.
3. Your harmony parts are playing a little too identical to your melody part, making the piece dry and flat. Go for a nice full sound by widening chords and adding more notes where emphasis is needed.
I'm sorry to be so hard on an attempt that clearly took many hours to piece together, but it's just not there yet.
