Double posting so I don't confuse myself with all these different thingys
03:12:644 (192644|5,192644|2) - Piano starts 1/4 earlier here, you might want to take note of that added a chord just before
03:21:491 (201491|6,201683|5) - Not sure if you want to but you can probably squeeze in this 1/6 piano here added on 
03:22:548 (202548|2,202741|1,202933|0,203125|2) - There is also a piano sequence that goes up in pitch here, you can probably do a stair-to-the-right pattern here for the left hand added
03:29:369 (209369|4,209369|5,209369|3) - The chord here starts on the next measure line actually (on the red line) fixed
03:29:691 (209691|4) - think you missed a piano thing here changed that first note to a chord
03:29:991 (209991|0,210041|1,210091|2) - Suggesting a 1/12, the grace sounds faster than a 1/8 yeah sounds about right. fixed
03:35:264 (215264|5,215332|6,215400|4) - Shift this to the left by 1 column, quite sure the 2nd note is of the same pitch as 03:35:060 (215060|5) - shifted
03:37:022 (217022|5) - Think this is a 1/8 grace changed indeed to 1/8
03:37:566 - Snaps should be as follows (highlighted notes are the only ones shifted, the 2nd note there is on 1/12:wow o_o thanks man, i'm bad at snaps
* 03:38:944 - Suggesting something like this since the last 2 beats there is a skip/grace beat so it's better to kind of separate both of them instead of doing them as a chordthat looks like a cool pattern, fixed
03:46:487 - Taking note of the accents in the piano here, you can potentially break the stream to do a chord pattern here just to map to them:looks good!
** 03:55:269 (235269|2,235301|1,235333|0,235397|1) - The anchor here on column 2 is rather hard to execute, 03:56:102 (236102|6) - the anchor on 6 here is also hard to execute, quite a big change but i suggest:oof. yeah agree that that pattern is kinda dumb, changed to your suggestion since it's about the best i'll get
03:56:935 (236935|0,237064|1,237192|2) - Not too sure why are they 1/6 lagging behind those drum hits oops, fixed.
04:05:141 (245141|0,245205|1,245269|2) - This is 1/8, not sure if you plan to change it however did that
* 04:13:987 (253987|3,253987|0,254083|1,254083|5,254179|2,254275|3,254371|4,254468|5,254564|2,254564|0,254564|6) - Personally think that you can do a more grand/intense/strong build up here:
Not too sure if you're a fan of big chord hammers but this is one of many ways you can do it:the  hammer was a bit awkward for me personally so I changed it to a simple  hammer: http://puu.sh/pmviy/a82fd3cba7.jpg
04:33:506 (273506|3) - Think this can be a 2 note chord considering how you layered this part added
04:35:237 (275237|5) - and this can be 3 added also
04:42:737 (282737|1) - Suggesting to move up by 1/4 because 1) it's a ghosty 2) for drum thing did
04:55:044 (295044|4,295044|1) - Think you can shift these upwards, same reason as above coincidentally did also coincidentally
* 04:56:294 (296294|1,296294|2,296487|5,296487|4,296583|2,296679|1,296775|4,296775|5,296871|3,296968|2,297064|1,297064|0) - Think you can structure this like:cooL
** 05:06:679 (306679|1,306679|2,306679|0,306968|0,306968|2,306968|1,307064|2,307064|0,307064|1,307352|1,307352|2,307352|0,307641|0,307641|2,307641|1,307737|1,307737|0,307737|2) - eeeh i can only hear notes on:discussed with you on discord
** 05:13:025 - the pattern here is... just really hard to execute well, i think this will work better:agreed and fixed!
