Regarding the 'average' version that got so many clicks and likes, we didn't refer to yours, but to other Tyros videos, such as the one Dnj gave as an example below the Audya video. I guess there is some kind of 'multiplier mechanism' involved with the number of clicks.
What your version is concerned, I noticed that it is a style and no midi file. One thing you could change is playing the fast repetitive pattern (the main melody e g c e g c etc.) with soft saxophones, that's not typical to be played by the trumpet(s), the brass rather throw in short chords.

I quite like this real orchestra version of German Max Greger with a radio orchestra, it's close to the original and BTW it's a nice landscape in the Alps, too:
