00:30:495 (1) - um, something is wrong with the end of the slider. You don't have to fix cause the slider is ok, but looks kinda weird.
00:10:665 (1) - Flip, 00:12:021 (2,3) - Stack to the left of the straight slider, 00:12:699 (4) - Move closer to the stack. :)
00:08:631 (3,4) - This is very preferable, but its common for mappers to use the same slider but copy and flip it. Please do!
00:08:461 (2,3) - Slider does not go with the flow of the circle, please move the circle over to the right more.
