I'm not a fan of the bassline that comes in (I find it overpowering at times), but everything else used in this piece was EXCELLENT. The piano was sublime, the strings provide very nice backing chords and rhythm, and from 0:35, my jaw just dropped.
What I would have liked is a proper change of dynamics (like what we see towards the end, when the bassline drops and everything else plays; it goes slightly softer). And buildup. 0:35 onwards would have been a very, VERY good buildup section. If you're planning to remake this or use that fragment in another piece, please see what you can do to build up the tension and let it go at the climax. It's a jaw-dropper as is, it can be even more of a jaw-dropper.
I enjoyed this piece. Knock the kinks out, polish what's good and you're on your way!
