Good, lively right hand playing and nice keyboard switching to the G70 in between. You could try to use the G70 keyboard also for the brief insertion of notes right after "You're the one that I want", these 6 fast notes following, because these are not part of the main melody sung by John Travolta etc. (I often do these quick changes on the pipe organ keyboards).
Reacting to what DNJ has just addressed: although your right hand playing is lively, in order to be enthusiastic about your renditions I would need your left hand to do more than the rhythmic chords thrown in, e.g. by removing the bass line from the midi file and playing it live with your left hand, and I would like to encourage you to make your own midi file instead of getting a custom one. Using custom midi files, from my perspective it means playing something others have prepared for me, even if you are adding very lively live parts to it.
But consider that this is my view of somebody who has spent more than a decade of piano and pipe organ lessons. Using custom third-party midi files will always mean "B-performance" to me.
So, as a suggestion, why not try to take out the bass line from the midi file next time and play it with your left hand.
