These two difficulties have different timings. Change Ex Normal's timing to Ex Hard's timing.
Ex Hard:
01:48:66 (12) - This note can easily be thought as part of the stream in this combo, please move it away. Just a heads up, you shouldn't really follow what distance snap forces after placing the .5x timing section.
02:29:45 (1) - ~ I don't really know why you've put .5x timing section here.. it would have made more sense if you put it at the start of the slow part (02:26:432), but honestly I think just having it normal would be fine.
02:21:25 (4) - Eh, I don't know why you put .5x here either.
Ex Normal:
This is so slooow.. it's best that you raise the slider velocity.
01:48:63 (1) - I think you should delete this beat, then extend 01:46:68 (1) by 1/2. :)
Have a star.
