Since you said the file already working, I will start to mod it then. Please update the hitsound along with the mod.

01:56:980 (116980|2) - 02:10:886 (130886|1) - These two are 1/4 not 1/3, it's quite obvious to hear here when you compared with other 1/3, this one is faster so 1/4 is the correct snap.
01:58:954 - The LNs here are quite confusing tbh, to be more exact the LN you put at 01:59:212 (119212|2,119341|0) - , because they don't follow guitar anymore even when you did follow guitar with the LN, Which cause the major confusion when playing because the differences are quite large in snap. If anything, the LN snap should be like this:
http://puu.sh/AXGwn/899a0586a2.png 02:00:178 (120178|2) - The note isn't 1/4, there's actually 2 1/6 sound at 02:00:156 - and 02:00:199 - , so if you plan to map guitar, you should do it at 1/6.
02:01:594 (121594|2,121723|1) - These 2 snaps are
wrong. They should be at 1/3 at 02:01:615 - and 02:01:701 - , if you need comparison, it supposed to be the same as the snap you put at 01:57:753 (117753|2,117839|3) - and 01:59:555 (119555|1,119641|3) -
02:02:560 (122560|2) - This LN is at 1/6 actually at 02:02:517 - and i'm not sure what you tried to follow for 1/4 at 02:02:495 (122495|0) - because there isn't any clear sound to map here, so it should be like

02:19:942 (139942|3,140199|2) - Again, the LNs here are quite obvious at wrong snap, It should be at 1/3 and 1/4 respectively, The screenshot should be like
http://puu.sh/AXGSd/4ba6e0fabb.png (started at 02:19:684 - ) , if you need comparison again, it should be somewhere similar with 01:56:637 -
Not sure if i miss anything, but these all are the snap that's quite obviously wrong and isn't allowed. (the rest of snap that looks wrong are actually the 1/4 you simplified to 1/2 , i can somehow still tolerate that so i don't say anything about that yet. it's more on the subjective issues)
