feedback for feedback

my first piece was performed on wed. and went relatively well .
although it was the end of class and the feedback was minimal it was still constructive.
-the first comment was that it sounded very jazzy - even though i wasnt necessarily going for that approach it just goes to prove that if you take a bass for a walk people will immediately be reminded of jazz.
-the second comment was that it sounds somewhat tonal - all chords and basslines were based on my atonal chord progression, in respect to the bass you can walk pretty much any series of notes and have it sound quite tonal-depending on what it is being played along to.
-the third was a comment on the rhythms - the overall rhythmic scheme was quite simple and along with the jazz sounding comment i think my revisions will have a focus on more complex and interesting beat patterns.
-the last comment was on the role of the bass as the accomp. - I was trying to get an equal division between piano/bass as solo/accomp. but it is difficult to make pizz bass predominent. i included some arco markings at the end of my second piece when the bass plays the main melody, this will foreshadow the bass as the dominent solo instrument of my third piece
i'm currently in the final draft of my second piece and quite pleased with it, i'm looking forward to hearing it performed on real instruments.
cheers
