Really liked it
I really like the beggining, the piano chord progression really draws your attention and almost gives you this anticipating feeling.
I hope you dont mind me giving you a couple suggestions and I know you've already got this, but since the chord progression is litterally the same as Dream on and only slightly off on a couple BPM, it DOES sound like the chorus to Dream On... I understood completely where you come from, it's impossible to find a completely original chord progression, but since most of your song consists mostly of just the same chord progression just played by different instruments, it's hard to get away from it being literally a fairly close copy of Dream On, I simply suggest changing the melody a bit... make it more complex and it could possibly lead away from that similar sound. Or possibly change the litteral chord progression slightly, wether by it's notes or rythem. Even a change of instruments could change it from sounding like someone is bound to sing "dream on", that orchestral thing you got going I noticed really helped with making it it's own thing. Maybe change what the guitar is playing or maybe the drum feel because to me personally those feel closest to the similar sound of that chorus.
Please, don't fret, this is better than most of the crap that's in the audio portal these days.
