Hopefully I will not be very brutal
Normal
00:04:654 (1) - Sliders with more than 3 points looks odd
00:07:115 (1,2) - Make this as one long slider
00:09:557 (1,2) - Shorten both to red ticks like so (You can change the curves as well)
00:11:423 (5,1) - Extend reverse slider and remove circle
00:16:808 - I know you're trying to emphasize the rhythm in this section, but for a normal it might be a bit confusing
00:26:500 (6) - Replace with circle and add another circle in the next white tick
00:27:115 (1,2) - This looks weird, consider changing to something like this
00:29:269 (1,2,3) - Again, too confusing, replace these with 4 sliders
00:34:500 (2,3) - This really abuses slider flow, change it
00:36:962 (2,3,4) - ^
00:39:115 (1) - Again, looks weird, change it like this
00:48:423 - Not sure what you are doing with this one, its not on a correct tick or something
00:54:192 (2,3,4) - A bit hard for normal
01:02:808 (4,5) - ^
01:07:962 (4) - Put this on a blue tick is confusing (Again, this is normal diff)
01:20:962 - Put a circle here to end
Overview
This diff needs to be nerfed since it is not exactly a normal at all (Normal is supposed to be under 2.5*), and if you don't want to nerf it, make a lower difficulty as you need at least a normal to make this rankable. Also, the flow in this is quite weird. I highly suggest you to do that in harder difficulties like insane or extra as flow is not supposed to be awkward

Hard
00:07:115 (6) - New combo here
00:11:423 (8,9) - Slider and flow, you get the idea
00:16:346 (6,7,8,1) - This might be a bit hard for Hard, decrease the spacing
00:17:192 - Move this to the previous red tick
00:20:039 (2,3,4) - This pattern is nice
00:24:654 (3,4,5) - If you're gonna stick with this pattern, move the sliderends on top of the next sliderhead to make it less hard
00:36:962 (1,2) - At this point I'm not sure if abusing slider flow is okay but just in case change the flow
00:42:808 (5,6,7) - Not necessarily bad, but not quite necessary to have sliders
00:46:808 (3,4) - Slider flow, optional to change since this is better than previous situations
00:48:039 (5,6) - Again, unnecessary sliders
00:52:654 (6,7,8) - ^
00:55:115 - Put a circle here
00:56:346 - Here as well
Overview
Again, flow is bad at some points, but it's better than Normal mostly. The ending imo is good

Closing Thoughts
You should focus on flow as of now, as your rhythm emphasis is quite good. This map also needs an Easy since the lowest diff has to be under 2.5* to be rankable. This song could also be a lot harder so if you want you can make an Insane and Extra as well.
