Heyyy what a cool map you have here
I thinks there's some stuff which can be fixed
The sliders at the very begining seems very weird for me ...
I think sliders like this :
-
https://osu.ppy.sh/ss/4967560-
https://osu.ppy.sh/ss/4967566Will be more apropriate, less hard and more friendly.
For the timming 2 of slider velocity is not good I think, 1.92 is better for CtB.
And there's some object which are not snapped use ctrl+maj+a to see the details.
But keep going, it's realy fun to play, I'm not an experimented mapper, but I'll hope I'll help you
