I've played ToS many times and I don't even understand those difficulty names. I'd rename to Normal, Hard, Mania.
Base
Tick Rate: 2
00:24:89 (1) - End 1/2 beat earlier to go with the music.
00:27:53 - Add a beat here (white tick)
00:37:72 (2) - Delete this. Distance snap accordingly.
00:39:04 (3) - Extend 1/2 beat, delete 4.
00:41:87 (1,2) - Really confusing here. Listen to the music and remap this.
00:45:27 (3) - Shift back 1/2 beat. Distance snap accordingly.
00:46:02 (5) - Extend by 1 whole beat.
00:47:72 (1) - Shift back 1/2 beat, Extend length by 1/2.
And just so you know, the song loops at around the 1 minute mark, not where you ended on Base difficulty. You can either keep the length as is or you can map until that point.
Master
00:05:08 - You can add a beat here. (red tick)
00:05:27 (8) - Turn this into a 1/2 beat long slider. Distance snap accordingly.
00:06:40 - Add a beat here. (white tick)
00:12:62 (2,3,4,5,6) - Take the repeat off of 2, delete 3,4,5,6, Add a spinner here. (from 00:12:81 to either 00:14:32 or
00:14:70, all white ticks)
After 00:20:36 (5) - Can you fill this gap with something?
After 00:45:27 (1) - See above.
00:53:57 (5) - Delete this.
01:09:60 (1) - Extend 1/2 beat.
After 01:16:40 (4) - Fill in the gap.
Also, I would map to the end of the 2nd loop.
Arcane
00:05:83 (10) - Distance snap from 9. I always click too early here.
00:34:70 (1) - Delete this. New combo at 00:34:89 (2). Distance snap accordingly.
00:53:57 (8,9,10) - Doesn't sound good with the music. :\
01:37:34 (1,2,1,2,3) - Don't keep the player at one spot the whole time. It's boring.
Overall, a good start, but it needs some work before I can star, much less bubble. Good Luck!
