Great song, I like the mapping style and especially the Extra difficulty!
Maybe make the slider-border white and remove overriding of the slider track color, so players with beatmap skins enabled (myself included) will have easier time with reading?
SliderBorder : 135,158,220 // 0,0,0 is good.
SliderTrackOverride : 27,67,62 // This line needs either removal or to be black.
Lacks spinner after (01:27:232).
Hard difficulties need spinners so players will be able to compete for #1s and the other difficulties also have them.
(01:13:683 (1)) - unsnapped slider end.
(00:06:020 (4)) - should be snapped to (00:06:022) instead!
