Hey,
The introduction sounds very film-score-ish ... and it sounds very very ominous. Actually, it sounds like a prelude (which it happens to be), so good job on matching your title with your piece! The orchestration of the chords provides a lush sound, which is another good thing about this. I also like the fact that there is coherency in the piece, which is what so many pieces lack. I feel that you could have used more contrary motion and more independent lines, just to create interest. The ending was very befitting of the piece, imo ... I think that the last chord is quite acceptable, and a seventh chord would only be out of character.
good work! I enjoyed listening to it (A little more length would be great, but then again its a prelude, so you fit the bill)
