Just from listening to it, it sounds like a seriously dark spy theme.
Anyways, the guitars are very emotionally pleasing to listen to. I think this has some great potential. I'm not a video game music person though, so I can't really give any advice on the mastering, as there isn't really any. I didn't find it too repetitive or anything. I was kind of hoping for a VII7+9 chord in there somewhere, though. :P
Anyways, It's very nice. 5.5, 4.5/5. I can't find anything wrong with it, although it could have more effort put into it, perhaps.
I'd appreciate if you'd look at my songs and critique them as well. Thanks. n.n
