Your offset sounds a little wrong, try 18907, this also makes your new combos line up with the down beats
Combo colours are allowed to be the same color but not too close in shade, your combo colour 1 and combo colour 2 seem very close
00:20:180 (1,2,3,1) - Could just made this a square, right now it looks a little off
00:20:808 (1) - Overlap with this and 00:21:436 (1) - seem very ugly
00:21:751 (2,3) - id recommend going into a sharp angle rather than a wide angle
00:22:379 (5) - Overlap with this and 00:22:693 (1) - seem very ugly
00:24:578 (5) - Control + J this and rotate it so its horizontal rather than has that angle and it might look and play better
00:24:892 (6) - ^
00:25:206 (1,2,3,4,1,2,3,4) - with the incorrect offset this sounds off, might sound better with the correct offset, might look better if you put a bit more distance between the 2 and the 3
00:35:494 (2,3,4,5) - this and the slider before it dont flow well which is crucial for bursts and streams
00:36:986 (4,1) - Way too close
00:44:054 (1) - Give this some emphasis as there is clearly a beat here but its just continuing on from before
00:45:703 (6,7,8) - looks a little off
00:46:881 (5,6) - the big beat is on the 5 yet you emphasis the 6, change direction on the 5 rather than the 6, example http://puu.sh/tnR5Z/1b1fa40a25.jpg
Continuing on from before, you emphasise it that time but fail to do so from now on, if you are going to emphasise the first beat after the down beat then continue to do so since you dont do it here
Basically just rince and repeat what i said above
01:03:829 (9) - Looks out of place
01:09:169 (13) - I wouldnt use kick sliders to emphasise azer's voice, i'd use it before so you can add space between the slider and the notes to emphasise thanks to stack leniency
01:19:536 (1,2,3) - You can make 1/2 jumps here, feels undermapped without it
01:21:735 (1,2,3,4) - please use the polygon creation tool and make a square when doing this, just make the square to 1/3/2/4
01:32:651 (6) - Personally feels like too much spacing, repeat that for all continuing parts that use this
01:40:269 (13) - Slider into spinner makes this feel very under whelming for the end of a song, id use a bigger spacing for the last stream and end on a note and not a slider
