OK here's my list of suggestions, based on the timing which I suggested.
Firstly about the Distance Snap, if you go through the map using Auto and see where the cursor has to speed up a lot to hit the beats then this is where you really need to use Distance Snap. Also it would be nicer if you stacked more notes that are close together on the timeline and unstacked the ones which are further apart..cos your stacking is a little inconsistent.
To clarify, by 'tick' I mean the smallest division on the timeline, and since it is 1/6 timing, a red tick would be a '3rd tick' and the '5th tick' would be just before a white tick etc.
Normal
00:41:980 [7] Move the slider so that it starts at 00:41:919 (5th tick) and ends at 00:44:101, then place a beat at 00:41:556
00:49:253 [7, 8] Move these onto the nearby white ticks
00:54:283 [1, 2, 3] Move all of these one tick back. Also you may want to replace this combo's [7] with a slider to prolong this note
00:59:010 [6] Move this forward onto the 5th tick
01:00:677 [5] Move this to 01:01:374 (2nd tick)
01:01:980 [6] Move the slider so that it starts at this time (a white tick) and shorten it to end at 01:03:798
01:04:465 [2] Move this one tick back (5th)
01:06:828 Add a beat here (2nd). Also for [6] you may want to replace with a slider as before
01:10:647 [6] Move this back to start at 01:10:525 (red) and shorten this slider to end at 01:11:434 (white)
01:11:798 Place a note here
01:13:434 [5] Move the beat back to here (red) or possibly prolong?
01:17:616 [5, 6] Move these both back one tick (white)
Hard
(This isn't an extensive list, use the Normal suggestions as guidelines)
00:06:707 [1 to 7] Move these all forward one tick (to white)
00:40:162 [5] Extend this slider to end on 00:40:889 (white)
00:41:798 [2] Delete this beat
00:51:071 [1,2] These two end/start at the same time!
00:55:995 [7] Move the beat to this specific time (red)
00:58:889 [6] Extend to end on 00:59:798 (white)
01:01:859 [6] Start this slider on 01:02:040 (a 1st tick), but it might be better to replace this with beats/ a long slider or something...
01:11:010 [6] Extend to end on 01:11:798 (white)
01:13:616 [5] Move so the slider starts here
01:15:071 [2] Extend to end on 01:15:798 (white)
01:19:071 [1 to 18] These are way too difficult! Can you play this bit perfectly?
01:25:192 [2] Move this forward one tick (white)
