Awesome

Haha this is awesome. Specially the BUS part. Can't imagine driving a bus nonstop for 20 years lol.

Not bad

This is actually pretty good. Some parts are a bit muddy though, you got too much stuff playing on the same frequency in certain parts of the composition.

Piano

The piano needs some work. I see you got some reverb going on, you need to edit the velocities to give it a bit of a "realistic feeling." There's something odd about this piano, did you do any distortion to it? The fade out end is good.

Interesting

This is a pretty interesting concept that you have going on here. I hear some potential in here, you should try to clean it up a bit. Perhaps throw some reverb on the piano and edit the velocities on the notes.
