You could try to improve how two sliders flow into each other. For example 01:14:314 (1,2) . If you rotate (1) by 15° couter-clockwise, it's more confortable to play and more pleasing for the eyes imo. This applies to sliders followed by a circle, too. Try to implement that throughout the map (You don't have to do this everytime though ^^)
02:34:814 (1,2) , 02:36:814 (1,2) , 02:38:814 (1,2) , 02:40:814 (1,2) - Not 100% perfectly aligned. (By three pixels or so)
