First, please don't post music for review on my profile. If I can get to it, I'll get to it.
Second, the music suffers from a. an incomplete blend of harmonic styles and b. the stratification of stylistic devices.
People are saying they don't like the beginning because of the overlap between the D major and minor modes you use, and I can't say I disagree with them. It's just not a very effective way to set up the piece, especially since it never comes back again. The last thing you want is to make the opening unidiomatic. There are better ways to blend the two scales through the use of a compound mode, but not both of them overlapping. It just sounds jarring here.
Secondly, the styles are very varied and I'm not sure if it's for the better. The second section with the percussion was pretty okay, but the piano sections don't blend with anything else in the track before the reprisal of the second section. Also it harmonically becomes very cliched without much thought to varying it at all. That much I can tell. What "sounds good" isn't always the best answer.
All in all, the track is extremely unfocused, regardless of how it was compositionally put together. You have a lot of good material to work with, it just doesn't blend.
