00:33:401 (1) - This is nice, but it's not symmetrical.
Use this code:
240,8,33401,6,0,B|223:32|256:45|256:45|239:110|239:110|192:109|157:127|157:127|231:192|183:264|183:264|199:337|256:378|256:378|313:337|329:264|329:264|281:192|355:127|355:127|320:109|273:110|273:110|256:45|256:45|289:32|272:8,1,982.300029977418,6|0,0:0|0:0,0:0:0:0:
It won't be symmetrical on the top so adjust the slider velocity slightly, or shift the node in the middle, but keep the X coordinate at 256
01:44:835 (1) - Could be a bit nicer symmetrically. Like, the curve on the right is good but the one on the left makes it look kinda weird lol. I think some of your slider arts could benefit from being done like symmetrically in the center, before being shifted. Like set them up in the center of the screen using symmetry, then rotate/move them after you're satisfied with the shape. Maybe its something to consider for futire maps tho
02:51:151 (1,2,3,4,5,6,1,2,3,4,5,6) - Not really a fan of having the circles overlapped. I think you could just keep them spaced and it would look nicer and more consistent with the grid style you had earlier.
03:53:676 (1,2,3,4,5,6,7,8,9,10,11,12,1) - Felt kinda forced. I don't think you have a lot of momentum going into the spaced streams so imo its not good to space them that much.
04:11:676 (1,2,3,4) - Since you're following the flute, its not good to map the red tick imo... I would just make them 1/2 sliders. The extra clicks kinda throw off the rhythm a bit for me. Applies to other sectiosn if you agree.
05:16:097 (1,2,3,4,5,6,1,2,3,4,5,6) - I actually thought these jumps were kinda small by comparison to the section's intensity lol. You could make it a bit bigger if you want imo.
05:19:886 (1) - Same as first point, I guess just reuse the slidercode I gave.
05:25:730 (1,2,3,1,2) - These all sound a bit early. Can you double check the timing?
