I really like how somber the vibes are with Sitting by the Docks. It's quiet and unassuming, with a really funny transition into the next song at the end (and I mean that in the best way possible).
The synthesized instruments in the second track work great for an alien spaceship type setting, though it still has a similar somber feeling to Sitting by the Docks with a pinch more dissonance. I think it helps the transition a bit more, though I think that lower pad might be playing just a little too low so that it sounds a bit growly. Moving the song up a few semitones or maybe playing the chords an octave higher might help a bit with that?
Escape!! Has a great melody, lots of tension and movement in the bassline that perfectly captures what it's going for.
Well That Sure Was Something caps it off nicely, returning to more familiar sounds. It's back to the more somber and wistful vibe, but the pad thing feels like a nice reference back to the alien ship. The melody and chord movements here felt just a bit chaotic, but the vibes were still there. Great submission overall! :D
