sure, there may be influences of Rachmaninoff & Debussy. But i would hesitate to say that these influences "consume" the piece & make it unoriginal! There are harmonies in this piece which would not be found in Debussy or Rach. However, i do agree with your thoughts about it being more of a "romance with little conflict between the piano and the orchestra". And, i'm happy with that. In fact, that may be what this concerto becomes eventually.
