Hey EagleGuard,
This is a solid song! I loved the intro, it has a nice feel of urgency to it that I really dig. The strings you used in the introduction and throughout the remainder of the song were a little bit too loud compared to the other instruments. It created a bit of an unbalance within the song. Perhaps you could turn them down slightly and add a little reverb to them so that it blends better with the other electronic elements. Otherwise though, I must say that I generally love the mix of the two. I have to admit that I didn't really see this as an ambient piece, mainly due to the percussion, strings and the guitar work. Everything is a tad too loud to be considered 'ambient' (though my definition of ambient is more relaxed 'background' music, and I could be completely wrong lol). Back to the percussion and guitar work. The percussion was nicely arranged, coming in at all the right parts and giving the song that nice upbeat quality while the guitar added some tension to the song.
The only other gripe I have about this is the ending. It sort of just trails off. I was expecting a suspenseful finish.
In my opinion, this would work great in a game. I agree with BFeltMusic. The song definitely reminded me of Mass Effect. Based on the instruments you have used it would suit well with the FPS genre, though I'm positive it would do well in others too! :D
I think this is a great song overall! Keep up the great work! :)
