Your changes to Date are good. The map seems somewhat smoother.
The Insane version is fine so far.
The Hard seems fine so far except:
00:30:507 - This slider
00:31:928 - And this slider
These sliders just didn't seem to fit for me. Try only making them return once and then have a note after instead which leads to slider in between them.
The Easy needs to be easier... xD :
The amount of returning sliders in it got confusing. Try turning them into longer sliders instead of returning ones.
00:31:928 - someone who is reasonably new to the game might not be able to hit this note. I'd remove that.
Basically, on the Easy map, but yourself in the shoes of someone who has played the game for a week or two, then consider changing a few things
