This is marvellous! I feel it needs to be extended. This seems like a set up for something that never comes. Bring this song to it's proper pinnacle. And yes I can't stop listening to it. It's like the execution is lacking somehow. Like the rest of the song is missing from it's place. Add to this shape it make it what it was meant to be.
I am expecting grate things from you. Don't let me down.
You bring up a very good atmosphere, but need more develop in melody.
I like how it starts soft, then the trumpets come in, then it really gets going. I think it might have sounded better if the humming opened up to a vowel sound when it crescendos at 0:45, but that's my own taste. As it is, it's a really good theme. The drums are cool, and the flute run near the end fills it out nicely.
Please contact me if you would like to use this in a project. We can discuss the details.
