i have to disagree with you because i dont think i break any flow at that section , its just a strongly emphasis on the slider , its still pretty straight forward and i dont think the flow to the slider are uncomfortable
considering since i think it played really well , i mean its not that unreasonable since its not a high bpm song , i think it is acceptable doing this patern in low bpm song :)
i would say that 00:15:893 (3,4,5,6) - this one give much more intense than 00:15:098 (1,2) - , with the second one got more instrument on it, i think it is pretty reasonable
