Well, for starters, there are parts where the piano and guitar comp at the same time. It clashes. Badly. Speaking of the guitar, why is he using distortion? In an old-style big band thing like this it should be clean. And with 18 gauge strings. The distortion makes the whole thing sound dirty and slightly off, jazz should be right on. Also the beginning is out of time, though that might be because I'm not used to listening to Japanese. Also it should be with an acoustic piano and upright, acoustic bass. It also has the same problem that a lot of Japanese jazz does, it swings too much. Usually on faster things your swing straightens out a bit, and on slower things it's more exaggerated. Also, it had no dynamics. Also it sounds overly simplistic, more like ska than proper jazz. Which is the major complaint with Japanese jazz (for the most part), it's more ska than jazz.
And why is the guitar player the only one with a solo? No trombone? Saxophone? Piano? Not even a nice vocal solo? She's a good singer, I'd like to hear her improvise.
And the ending kind of made me die inside, it was so cliched.
(You asked what was wrong with it.)
