Also the arrangment dosen't match what you are playing starting around bar 64.

I hope you've managed to get through it ! But if not here's a few tips I would have, first practice those harmonics, there are a lot of good videos on youtube that give you exercices (Josh lane has a great one), but those definitely need to be mastered before you attempt this piece. If not you can always simplify to begin by just playing normal notes. Second I would start at half de tempo and simply try to keep it steady, this piece is very repetitive and creates this sort of calm out of that repetition, for that to be most optimal, I would try to keep the tempo as even as possible, going fast here at the expense of accurate rythym detract from the piece. SO basically train your hands, start slow, focus on rythym slowly you can crank up the tempo and you'll feel much more secure. And if all fails perhaps you can simplifiy the arrangement by looking at some easier piano versions and combine them :-)
