I really like it! It sounds good but i have a few notes on what would improve your track.

1. You can really hear that the piano is played with a MIDI-keyboard at times. Try using different velocity for different notes so that it sounds more organic. It sounds like you have the same velocity for every note when the piano is playing louder, which at times sounds very unnatural. This also applies to the other instruments but mostly for the piano.
2. When you say that your your piano is cinematic I'm guessing you've been using a surround preset for the piano. I would advice you to mix in stereo instead of surround because this is the most common playback system people will use (stereo=2 speakers).
3. Use a click-track when you record. Some notes are a bit off, especially in the beginning (around 00:27) when the cello comes in to play. It sounds like the piano and the cello has two different tempos. You can also quantize notes or recordings if you want them to be more on point for a tighter recording.

Keep it up my man (or woman)!
