[Hard]
00:01:764 (3,4,1,2,1,2,3,4,5,6,1,2,3,4,1,1,2,3,4) - Aren't you mapping too much to the left side? Check this out
https://puu.sh/vAJI9/a2b1272813.png00:07:680 (5,6,7,1,2) - Same rhythm, yet the spacing is so confusing due to 00:08:102 (7,1) - being so close, it can easily be interpret as a 1/4 double.
00:10:215 (1,2,3,4,5,6) - Way too much stack. For example, kinda see a double "300" due to the end of slider (1).
00:14:018 (10,1,2,3,4,5,6,1) - Wow thing got harder here, 00:14:229 (1,2,3,4,5,6,1) - close due to stream right? Then why are these 2 00:14:018 (10,1) - so far. Check out the timing, only a 1/4 separate them.
00:14:863 (1,2) - Try to make a pattern that flow better, you're making a 180 degree mouse going top left then instantly going down right.
00:22:257 (2,3,4) - You hear it a bit too late. The triplet should be at 00:22:257 - , 00:22:363 - and 00:22:468 - . There is no drum sound at 00:22:574 - .
00:27:116 (2,3,4,5) - What with the sudden big jump here?! While this 00:27:539 (5,6) - is normal x.x.
You're making playing do a huge jump which is already challenging for this level of difficulty, and right after the big jump, instant triple stream!.
00:27:855 (7) - This could easily be consider an overmap, since the drum stream start at 00:27:961 - . There no drum sound at that part.
Some suggestion
Since you did put some 1/4 stream for the drum, don't hesitate too add some part on too much 1/2 beat.
For example here 00:20:673 - , there is a drum sound which can be a triple instead of always squarish pattern.
Also press ctrl+A. You should see something like this :

Another thing, I'm not saying that other GD are perfect, but try checking their difficulty, see what kind of difference there is in play and try to play it as well.
But they use different kind of slider, flow, while your is mostly straight line. (Don't worry most of us started like this as mapping as well)
