Sorry, I have to go to a clinic, so I only got to mod Rapaa!. PM me again to remind me to mod WAHOO! and it shall be done.
Rapaa!:
-00:17:11 (8) - Make this symmetrical on both sides.
-00:32:84 (5) - Realign the diagonal this is in with 4. Respace 6, 7, and 8 to make them look neat again afterwards.
-03:33:22 (2) - The starting point should have a Finish.
-03:35:41 (7) - Straighten this out.
-03:39:80 (6) - Line up with 4. Then respace the stuff after it.
-03:42:00 (5,6,7,8) - Whistles go here.
-03:47:12 (6) - Whistle goes here.
-03:58:10 (6) - Clean up the middle of this slider (make it more...symmetrical, I guess)
EDIT: Sorry, fell asleep before I could finish modding this before.
WAHOO!:
-00:12:72 and 00:12:90 - I feel like there should be beats here.
-00:13:82 (3) - Line up in the diagonal previously set by 1 and 2 unless you alter 2 to make this look more like a curve.
-00:27:54 (9) - New Combo mark goes here. I'm not a fan of combos over 16, but that's probably just a personal preference.
-00:29:55 (15) - Line up with 13 and 17.
-00:42:17 (9,10) - Move this over to the left slightly, given the shape you're forming with 11, 12, and 13. Just make sure the space between 10 and 11 is even.
-00:46:56 (3) - Make this shaped like 1, 2, and 4.
-00:51:50 (1,2,3,etc) - First off, make 1 a clicked beat. Then, remove the New Combo mark from it. Make what would have been 2 start 1/2 a beat earlier and make it an Etna slider. Put the New Combo mark on it. Then, remake the pattern so it flows the same way it did before.
-01:01:75 (14,1) - Delete 14, move the spinner back 1/2 a beat and then extend it 1/2 a beat.
-01:35:04 (5) - Line up exactly with 4's starting point.
-02:06:14 (2,3) - Stack exactly on the end of 1's endpoint.
-02:24:61 (6,7,8) - To me, it'd look better if you line up the endpoints of these sliders.
-02:57:35 (1,2,3,4,5,6,7,8) - This part just feels awkward to me. As if it'd be better if 2, 4, 6, and 8 were on the endpoints of the slider before it, not the slider after it.
-03:00:28 (1,2,3,4,5,6,7,8) - ^
-03:28:82 (11,12,13) - Lower so it's still even and 13 ends up on the starting point of 10.
-03:37:60 (4) - New Combo mark.
Starred.
