So... what's new?
It sounds as though you just added some spatial effects to a midi file you found on the internet and sped it up a bit. It's been done. To be fair, I think you have something going with the omitted right hand in the beginning. Having said that, it could only ever reach its potential in an original arrangement. On the GM piano it sounds so dull and lifeless. The reverb doesn't really do much for me (too wet imo). You should definitely automate sustain controls and maybe tempo fluctuations. Also try to offset the timing of some notes by a very small amount to make it sound more natural, espescially in chords.
After about 1m30s I don't really feel like I need to listen to it any further because I know already how it's going to pan out. If you do more VG tune covers in the future (and I think you should to get more practice) you should arrange them differently to give them your own personal touch and to keep the listener on their toes.
Keep it up.
