Not bad
It's not bad at all. It lets us know that you have a lot of ability. If I could give you any advice that sticks, let it be that music needs to be dynamic. The first bit of the song isn't really going anywhere. Then it goes into half time (really great effect when implemented correctly), but then it goes back into the same thing as it opened with. Just try to make your music always be going somewhere. Listeners need to feel like they are being led somewhere instead of just standing in one place. No matter how beautiful scene is, it's easy to get tired of it unless you're always seeing more beautiful scenes.
