currently the mapset consists 3 diffs, which are called normal, hard, and faster. the spread would be fine, but i think that the hard diff is more of an advanced or a light insane diff rather than an actual hard diff. i would recommend nerfing some patterns in the hard diff to make it an actual hard diff rather than an advanced or a light insane.
i'm not a metadata expert, but you shouldn't put anything in the tags which are already present in the artist/title/source field. so tags like yung lean, ecco2k.. etc are irrelevant, since they are already included in the song's title.
you also have your username in the tags. since you should write tags based on the song, not the map or mapper, it becomes irrelevant. if you had any guest mappers or collab members, it would be fine having their usernames within the tags.
so if you want to tag the map properly, you should search for the song on google or something, and you should put any relevant information to the song in the tags. also it is nice to have a note, where you got all those tags from. eg i found this https://genius.com/Yung-lean-and-skrillex-summertime-blood-lyrics site, which has a relevant information such as Frederik Okazaki as a producer.
