Six: nice chilling sounds, chords are nice; the synth-sound is a little bit too static during the play. Synths at 3:34 are flowing and fit well and aerate the mood. The drums have some good phrases, but sound sometimes hectic. To complete the sound characteristics, there could be a tone in the lower frequencies, like a bass (maybe in interaction with the drums). All in all good phrases.
seven: More minimal track with electro influences. The typical electro- “rim/ploing”-tone is too standard. The arrangement is more straight-lined than in Six, you know everytime where you are. Maybe a bit more variety in the melody and some breaks.
