I listened to the first track. The composition is great. You can imagine a story happening here. Very interesting sounds and moods. Personally, I wouldn't use the male voices you put. Perhaps the piece could have stopped around 2.40 and then a second piece starting around 2.45 onwards it could be another piece. But that's my first impression and personal opinion. Not sure also if there are a bit of distortion in some parts.
But overall I really like it.
