Having hitsounds with volume 80 on the kiai is fine, but I confess that it's strange to see this when the entire map doesn't go above 60 until the kiai actually starts.
maybe reduce kiai to 75% or increase the volume of the rest of the map in a subtle way
There's no problem copying Tags from another mapset, but don't do it in a dirty way lol
In https://osu.ppy.sh/beatmapsets/1112988 tags like "yumerios" and "tanzeem" were used because they are nicknames of players who made GD for the mapset, remove this from your .
