Hi there. I don't think something has to sound 'epic' to be 'cinematic'. Although I now associate the word 'epic' with 'bland' rather than cinematic.
Your music does have the correct constructs to work for parts of a modern day video-game for example, and if you were going for that, you've achieved it. It is pleasant enough to listen to and competently-mixed. Definitely not dislikeable. But that said, as a piece of music in and of itself, it doesn't really have an emotional impact on me. It has no emotional punch, that 'little something' that really gives you that gut wrenching moment, the bit that pulls on your heart strings. Perhaps if you'd strayed a bit from the pop music progressions, and hit a different chord that makes you go 'oh', something to surprise. Of course, a piano playing pop chords *does* work for a lot of people, so if you enjoy doing that sound and know your audience then that's cool too. This is just my opinion. Your mixing is generally fine, and spread generously across the spectrum, so kudos on the production aspect.
Good luck with your future work.
