Hi there!
trust
I just want to give my general opinion to this difficulty.
We have a lot of possibilites to express the song in a good way and these possibilities should be used. There are calm and exciting parts in this song; so why not expressing these as such?
Let's say the song is built up like this:
00:01:945 (1) - Just a calm intro Slow SV can be used to give the player a smooth lead in.
0:05:021 (1) - Vocals appear, it gets more exciting. I wouldn't change the SV, but maybe follow the vocals / change the density
00:11:175 - Guitar sounds, which is an unusual change in that moment with a finish off 00:13:868 (7) - here I guess that part is mapped alright, 00:11:175 (1) - I'd just map this with 1/2. 00:13:483 (5,6) - This is pretty much overmapped and doesn't really compliment the song. 00:13:868 (7) - How about a special slider to finish off cooler? An extremely round one, idk, it's up to your fantasy.
00:14:252 - Here's the "normal" part, so to say. Time for 1.00x SV, and normal stuff
00:26:560 - - Her voice gets more dramatic, excellently covered by the stronger getting instruments in the background No SV changes, but maybe an increasing of the spacing would fit.
00:38:868 (1) - Her voice changes again, to a less dramatic style, yet more powerful than at 00:14:252, to build up tension. Use some jumps here, and dont' cover 00:50:214 - this beat with a slider end, since it's too powerful to be wasted.
00:51:175 (1) - It gets a bit calmer right now. Less jumps, preferably slower SV.
00:57:329 (1) - The instruments try to lead-in the chorus, as you can see, they get more powerful. 00:57:329 (1,2,3,4) - That part is completely wasted with using so low spacing, increase it or also increase the density
00:58:868 (1) - Tension is released, the kiai starts (although I have to admit, the vocals aren't that powerful here). As said, it's not really too powerful, 1.0 or 1.1 would be cool here, just as you did. Hgiher spacing helps emphasising the fact it's a kiai.
01:20:406 (1) - End of the chorus, the song is slowly coming to an end. progressingly increasing the jumps, or something like that.
01:21:945 (1) - Instruments try to emphasise the song for a last time. streams were a good chioce here.
All these things said are to emphasize the song in a suitable way, but of course that's really subjective. It's how you could bring your maps to a new level, but if you don't want to use these things, I can't do much about it.
Just my two cents anyway. Good luck with improving your map!
