Waterways: I actually like the distortion. Great watery sounding track! I think I recognize the one flute from Massive, I love that sound.
Swimming Upstream: 5/4! Great groove.
Sunken Castle: Great bass! This sounds so cool! Nails the sunken castle theme of the name.
Plummet: I really love your rhythms. Love the section at 1:27. The effects are a lil much at that part but I really love the composition and instrumentation underneath.
Great work!
