00:26:749 (1) - sounds like this spinner is a 16th note too long and starts a 32nd note too soon
00:08:931 (4) - this slider should last for two more beats imo, rhythm stays consistent with the vocals and the sliderticks work well to represent the four note melody
00:23:113 (3) - this slider isnt really representing the vocals or percussion very well, should just be a single note. if you want to get back into vocals you could make that a slider after?
