Hallo there!
General(Taken from Italy)
Change offset to 784
Source is different on different difficulties O_O (actually now that I check it's just England that's different)
Actually you can remove all the timing points apart from the first one (unless it's for Kiai), I don't think they're needed
Italy00:06:431 (1) - Depending on how difficult you want this, you could reduce this spinner or put more space between it and the next beat
00:08:306 - What is this uninherited timing point for? I don't think you need this
00:15:806 - Same thing
00:17:212 (2 - 6) - Spacing, it's different from before and (6 - 8). Move closer together
00:22:837 (1, 2) - Same
00:26:587, 00:30:337 - I don't think you need these timing sections as well, especially since it's just for a spinner
JapanThis is REALLY like Italy. Also, its maximum score is LESS than Italy. WTF?
00:03:618 (end of 2, 3) - Spacing, I suggest moving the rest of the combo below this slider
00:05:024 (end of 5, 6) - Spacing, move one grid left
00:13:462 (1) - Don't like this overlap, you're used to half beat overlaps not quarter beat overlaps. I suggest moving it so it looks like the spacing at 00:04:321 (4, 5) (same time difference). Also, spacing between this and (2), move one grid closer together
00:16:743 (end of 2 - 1 of next combo) - Your spacing changes a lot. Do you want one or two grids between objects that are half beat away? I've been thinking it's one grid and my spacing comments have reflected that, but two grids happens so much I don't know which one you want. Whichever it is, pick one and stick with it. Spacing here should be closer together if it's 1 as indicated earlier in the song ...
... another good example of this is 00:21:431 - 00:22:368. Timing is the same here but spacing is not. Fix this as well
EnglandSee spacing comments above. Spacing for quarter beats is different: 00:02:446 (4, 5) and 00:04:321 (end of 1, 2) VS. 00:04:556 (2 - 4 of next combo) VS. 00:16:977 (1, 2) and 00:18:852 (4 - 2 of next combo)
Other than that not much else
HeroDerp. Spacing again. 00:02:212 (end of 2, 3). May I suggest making the slider repeat again instead, deleting (3), then moving the rest of the combo closer?
00:05:962 (2) - I suggest unstacking this from (1)
00:09:243 (end of 2, 3) - Spacing
00:10:181 (end of 3, 4) - Spacing
00:19:087 (1 - 7) - Erm ... you switched spacing amounts? O_O Even if you keep this move (1) one grid to the right
00:22:368 (1) - 00:27:290 (5) - Even further spacing now? Uh ... okay ... It's even the same as 00:27:993 (3, 4) which is a half beat ...
Most of these are pretty specific, apart from the really obvious spacing ones. Good job for your first map though. Lucks!
