I really like the second and the third track and the character in your music in general. I think the rhythm in the first track was clashing a little (the rhythm in the instrument tracks didn't meld very well with one another) and made it harder to listen to. It might also be that the instruments you were using were unintentionally accenting beats that worked against the time signature. I really like the idea of "conversations" though and the rhythms you chose to work with to evoke that idea worked really well. Great work!
