lots of parts of the map lack contrast imo. doing different patterns, making some parts of the map more difficult and harder than others, and other things as well can make the map fit the song so much better when done well and increase the quality of the map overall (you can also show contrast in different ways using things like rhythm choice as well!! )
there's so many times when objects or sliders or snapped to the wrong ticks. esp in a song like this when theres like 1/4, 1/6, 1/8 used it can be very useful to slow down the song in the editor to make sure you get it right !! ^w^
