Nice atmosphere.
My first music review is for you. You can feel honored (or not, it's up to you).
So... You succeeded to create a really nice ambiance, i particularly like the beginning for it. The smooth percu suits perfectly to the rest, in this sense . One mistake, according to me, is the rave-clubbing echo at the entrance of the first sharped melody. I think you should remove it cause there is no place for it (no offence, it's just my opinion).
The break with the piano is quite correct even if really sudden, but that's not a problem due to the atmosphere, and the use of this instrument brings a lil sad side that is great and makes think about a post-apocalyptical landscape (particularly when the long kinda mystic notes accompany it).
One last thing... unfortunately i don't really like the end, it's too different from the rest and i don't understand it.
I hope you'll understand everything, it's not easy to express myself about music in a language which is not mine.
PS : i gave you a 8 at the beginning, due to the 2-3 things that i find wrong, but the music is still playing and looping while i'm reviewin, and after 6 or more listenings, i really like it... ;) Well done.
