Doesn't look too bad. Out of mod steam atm, so I'll probably edit this later or post again.
All I can say at the moment is since there are so many sliders, there isn't as much to mod. Just take a look at all your sliders and ask yourself if you could shape them better. There a few I saw that I thought could be improved shape-wise, but this is a fairly small detail so.
Star'd.
Edit:
Loser
00:35:25 (1) - Nazi. Align endpoint with start a bit better? Then align with 2. The slider at 00:56:35 is like perfect, I think you could copy paste it actually. Right endpoint needs down like 2 pixels and it's perfectly aligned.
00:45:18 (1) - ^ Nazi. This one was really close to perfect too, lol.
01:06:69 - ^ Also Nazi
00:49:32 (2) - I think you should move this off of (3)
00:51:80 (1,2) - You could round these a big more and get a circle thing going with them.
01:08:35 (1) - Touch this up a little, it droops slightly on the left.
Also, what's up with (2) after it? Used linear instead of Bezier and it looks rather out of place.
01:11:66 (2) - Meh, I dunno. Same for following slider. I guess it's ok.
01:23:25 (1,2) - You know you could totally turn this into a heart right? Lol. xdd Do ittt. It fits the lyrics too.

00:17:04 (2) - Dunno about the shape. It's fine I think, but I think the shape could be improved somehow. Can you think of any neat shapes for this one?
00:25:32 (5) - Align. Should be down one and right either 3 or 4.
00:55:11 (2) - Reshape maybe? Hmm.
01:06:69 til either 01:10:83 or 01:13:32 - The slider gets rather lower on the screen here. Move this entire section up by.. 1? 2?
You could also flatten the slider or something.
01:18:01 (1,2,3,4,5) -Realign. It looks a little smooshed.
01:34:01 (2) - End point could be stacked a little more cleanly.
Captain
00:23:94 (3,4,5,6,7,8) - Uhh.. Align's a little wierd but I dunno.
00:27:80 (3) - Needs moar curve imho. Doesn't curve like (1) does. Endpoint is in a good spot, I'd bring the start up a bit so it curves more.
00:30:41 (2,3) - I'd bring (2) up a bit so it's in the middle of (1), I think it looks better. Then 3 has to go up a bit obviously.
00:36:48 (1,2,3) - I like these, lol.
00:45:58 (1/3) - naziEndpoint doesn't stack quite right.
00:48:49 (1,2,3) - These are supposed to be ever so slightly slanted right? Same 2 seconds later, and once on Pirate difficulty I believe.
00:51:59 (1,2,3,4,5,6) - Like this part too. Dx
01:23:45 (1,2) - Off by one pixel at endpoints if you want to be nazi about it. Same like 2 seconds later. Almost didn't mention this since it's nearly unnoticeable but meh.
01:34:01 (3) - This is a little off from 1. Also not grid snap'd atm.
Hope that wasn't too nazi for you.
A thought occurs though. I think you could fit one of those neat crossbones Larto did in 'You Are A Pirate' on his hardest difficulty, somewhere into your map. Might be worth taking a look at, could be neat. Needs a Pirate spinner imho. xdd
