It's quite an engaging piano piece and without going around "what could have been" scenarios too much, I'm simply going to say that you have a lot of potential in your hands to become the next Audiomachine.
Let's be honest, this piano by itself conceals a kind of power that could have been fully expressed by an orchestra, not really because the instrument itself is not capable of replacing an entire hall, but at the current state of things, it's not offering much.
Experimenting with chord progressions is surely a good expedient to build a basic structure for your piece, but sometimes it's not everything in a song, and while the dissonance in some clashing chords may give your piano an interesting sound, I think you could have played with other dynamics as well.
In fact you immediately start with a driving riff at a moderate volume and then it gets marcato at around 20 seconds in the piece. If it were intended to be a slow building piano, I would have started with a minimal pattern at a pianissimo intensity and then let it grow gradually in intensity so that it gives plenty of contrast. Here I think there's minimal contrast because as a whole, the piece is pretty homogeneous in both intensity and melody.
Overall, it's still a nice effort that quite matches the artwork of choice.
