Nice music.
It's remarkable the way you get a really (but mild) oriental sound, just using scales and some chords (not all) with 5ths and 4ths in the bottom. Surely you would get a stronger (oriental) sound with other devices (pentatonics, scales with augmented seconds, etc...). But it's OK, because it blends very well with the polonaise part.
There is only one thing I'm not very fond of, and it is, particularly in the first part, the "excess" of arpeggiated chords. I think it weakens the piece, I mean, it makes it sound more "¿corny?", and it belongs to another style. I know if you have wide chords there is no other way but to roll them, but I would figure out other solution (just my opinion, if you like it ...OK).
