These ones grew on me while I was listening to them. Although I found Peaceful Life and A Busy Town! the most enjoyable (they're so jaunty!), I liked Desolation a lot as well. I actually think keeping it simple with just a piano was a good choice for that theme, and provides a nice contrast to the "fuller" sounds of the previous pieces. Like in Beethoven's Moonlight Sonata or Satie's Gymnopedie No. 1, sometimes a solo piano provides all the melancholy you need, and adding any more layers could actually detract from that feeling.
