A lot of the notes need to be snapped properly in the timeline, preferably using a 1/2 beat snap divisor.
Basically this applies for every note from 00:05:23 (7). Sure, this particular note is only 00:00:01 off, but people do notice it when playing. I think this happened because you changed your BPM but didn't resnap your notes.
Also I noticed that there seemed to lack beat spacing between combos, which I kind of grant a little leniency towards, but it's still a bit dodgy. Some notes like 00:18:78 (8) - need to be spaced properly though.
Well it's not entirely bad, your timing seems more or less ok. If you want this ranked, you'll need to address these issues and also make at least 1 more difficulty, though preferably an easy and insane or something.
Also you could probably map a bit more of this song, say about 3 minutes in total play time.
