dance me to the end of times..
This is not that bad, I like your composition a lot, although it didn't change up too much. I believe it stuck with the same chord progression, and there never was a break of any sort, like a quiet moment to do something new and interesting.
I think the part that may or may not hold back the composition is the production itself. There are a lot better orchestra and choir sounds you can get for free, and there's quite a few tricks you can do to make a little sound like something almost real.
A great example of your style of writing and music working really well is my friend Taylor Mefford. He only used free soundfonts off the internet to make this amazing score, its definitely worth looking at to see the power of knowing how to master and use effects.
You can get it for free if you want to listen to it in your spare time. http://musicbytaylormefford.bandcamp.com/album/an-experiment-with-an-air-pump-original-score
But you really have some talent, I think if you practice and study up a bit you could probably do some super sweet stuff man.
Keep making music dude!
Please contact me if you would like to use this in a project. We can discuss the details.
