Dude, that sounds really great. Here are some ideas:

1) Introduce the music in the background earlier.

2) Make that background music louder and more noticeable.

3) Have the metal sounds (which sound really good, just make them deeper in tone) flow with the music. For the first few seconds, make them random, then start to form them to follow a rhythm. After that, transition them into the rhythm of the background music. THat's when you raise the volume of the music to make it on par with the metal sounds.

4) I like the vibe, but if you can then make it a bit darker, please.

I hope that I'm not overstepping my bounds with this stuff, but I think that you are definitely on the right track. Also, longer would be nice....
