The entire track is really good! The sound design creates a very cool atmosphere. The way you mixed the orchestral parts with these robotic sounds is really interesting. If it was a track to a video game it would fit in perfectly as backround music when you walk through ruins and fight monsters. But as a individual track it doesn´t work as well as in a video game.
The track doesn´t have a built-up or anything that keeps you going as a listener. The excitement stays pretty flat, sometimes it´s goes up like in 1:45 but immediatly goes back down. The track repeats itself after 3:00 (I think, the two parts sound extremly similar) which makes absolutly sense in a video game but in a song not as much.
I think while you were making this you had a video game ruin in mind and build it around this concept rather than an individual sound piece to active listing to.
Still, it is a cool track with a very cool sound design which, for itself is kinda repetitive but still interesting, yet inside of a video game would be brilliant.
