I've never heard a song in 7/8, it sounds wild! Really interesting musically. At 1:08 there's something that sounds a bit like a clav and I think the melody is a little busy if that makes sense? The break down at 1:40 is really nice and keeps things interesting. I think the bass overall should be tightened up a bit more. Maybe a bit less reverb and eq of the low mids. Overall really nice though, good work!
