Change AR to 3 or 4 for me 4 would be great
slider velocity is too high should be around 1~ same for distance scaling
00:00:999 (1) - ends too late 00:03:999 (1,2,3) are visible too early which will make beginners confused
Btw beginning should be made with only slider like that

https://osu.ppy.sh/ss/9246812it really depends circles only is just boring also make sure to make new combos every 4 or 3 objects at beginning
00:17:285 (1,2,3,4,5,6,7) - you can't place slider on blue ticks!! its not rankable here also you should try to place objects every white tick
00:30:999 (1) to 00:56:713 (13) - Remember About placing slider and making new combos!
00:58:428 (1) - looks odd something like this would be better
http://osu.ppy.sh/ss/924683601:00:999 (2,3,4,5,6) - too much overlapping happens it should be more clear like that
