Attention: Opinion!
I liked Tokyo, the other two were less good in comparison, so let me say something about Tokyo:
I like the instruments which are being used until 0:48. They are kind of funky/fun/cute the "wave" which starts at 0:48 is unsuitably melancholic. So keeping the style on the fun side would have been good.
There is another problem with the track though: It's very monotone, the background is always the same, the foreground (the wave) is only one texture. More variation, especially in the background instruments would do wonders.
Opinion over!
