The drums need work
It sounds like you used the presets and first drum samples you came across right out of EZ drummer or something. The kick drum sounds like someone tapping their finger on plastic, it needs more bass/boom to it. The snare sounds even worse, it doesn't sound like a snare at all :/
Wahnsinn has well produced drums in his metal songs, he's a good example of how they should sound.
The guitar tone could also use some improvement. It sounds a bit weak and could be louder in the mix (although that's probably because you're more for the orchestration then the metal side of the song).
Outside of the drum and guitar tones, everything else sounds great in the song. The orchestration is good as well as the composition and guitar riffs.
