I'll be the first to disregard Seibei's modding and proceed with my own.
Largely because Seibei is being too personal with this.
Offset wise, I thought this might require a reduction of 2ms to 5ms, but I can't tell if it's a sounds issue on my side or something so don't change (and inherently, there is no real need to change) the offset unless you are very sure that I am spot-on.
One highlight about this modding is, if none of my suggestions (in bold) for Normal are taken as stated below, both difficulties will have to be renamed to Hard and Insane, for the purpose of a less misleading classification of difficulties. Marked in red are modding which Seibei may already have mentioned.
Normal
00:45:13 (1,2,3,4) - Bear in mind that you are catering to a Normal audience, which means you should not really be including too many jumps which might throw off the average gamer. Hence, with this, my suggestion is that you alter this pattern so it is easier to follow, such as 00:39:75 (1,2,3,1), or a square pattern.
01:51:45 (1,2) - This, and similar patterns after the spinner, should be re-patterned into a normally-spaced beat because a 1/2 jump like this is indeed very unfair for a difficulty marked as "Normal".
01:52:01 (1) - This, and the next two spinners after this should be shortened by 1/4 beat.
01:55:03 (1,2) - Like in 01:51:45 (1,2), this should be changed. If there is a larger jump here relative to 1,2, I do not mind, but bear in mind what your difficulty suggests and what this difficulty is doing.
02:15:20() - A missing break.
Hard
02:16:54 (1) - This ended 1/4 too early. Lengthen this slider.
03:08:58 (1) - Re-snap this to the white ticks, drag the whole slider spinner on the timeline, until the two ends fit on white ticks.
This map is now starred.

There it looks nice! x3 Maybe i'll check in editor later, for kudosu *o* xD (but now i'm too lazy =o=)
