I agree with the others.
These were my first thoughts:
Strange pauses in the intro at 0:03 and 0:05. Sounds more like a noise gate than a piano player lifting hands off the piano.
The trumpet does not sound realistic. If you just removed the trumpet (and the rest of the brass) and fixed the intro I believe this would be a great track! Maybe also work a bit more on the drums for a more live, realistic feel. If something can’t pass for real, just don’t use it at all in a track like this.
I would personally prefer this track as piano only, but that’s more a matter of taste.
Cool ideas, but overall I feel it’s a bit muddy, and strange use of cutoff filters. Sounds like something’s wrong with the speakers rather than what you usually want the cutoff filter to achieve.
It’s a cool track though, but I would also remove some of the elements in the busy parts.
In the dubstep breaks I think the snare drum is way too weak.
