Hi there ... very interesting song you have here 
I'duction
00:20:836 (1) - This slider goes a bit high, maybe move this lower? Also, spacing between the end of this slider and the next one
00:26:288 (2) - Spacing. Move to the right?
00:34:255 (1) - Same as first comment, except it's a bit low. Move up and left?
00:47:045 (1) - Spacing
01:34:641 (2) - New combo?
01:34:641 (2) until 01:53:931 (end of 4) - The design here is mostly the same as the beginning. You should change it up to make it more interesting and fun to play
02:21:608 (1) until 02:45:720 (end of 2) - Same design again. Do something different
02:49:704 (1, 2, 1 of next combo) - Spacing! This jump is too far for the length and difficulty
Standard
01:34:641 (1) until 01:53:931 (end of 4) - Same as your easier difficulty, you should try to make some new patterns
01:55:189 (3) - This is pretty low. Move this combo up?
02:21:608 (1) until 02:45:720 (3) - Same thing
02:49:704 (1, 2, 1 of next combo) - Spacing again
Hardcore
00:17:272 (4, 1 of next combo) - Spacing, should be the same as (3) to (4) (also apply this to anything else like this, like 00:20:626, etc.)
01:18:496 (6) - Delete this, move the rest of the combo up
01:34:641 (2) - New combo?
01:34:641 (1) until 01:51:624 (6) - Erm, see above comments?
01:52:044 (1) - Shorten this spinner by one or two beats?
02:21:608 (1) until 02:45:720 (6) - Too much copy paste flip is not a good thing!
Extreme
Overall this just feels like wider spaced version of Hardcore with harder difficulty settings. I would suggest re - mapping most of this or at least changing the main patterns, but if not, most of my comments for Hardcore also apply here
The song is pretty good, but overall I feel that the patterns are overused (the result of too much copy pasta?). I think this has a lot of potential, so keep working on it. Good job
