Typically, meeting the criteria for a map's ranking involves having at least 2 BNs support it and meeting the osu ranking criteria. However, in practice, BNs often have their own set of standards when nominating maps, making it challenging to provide a definitive checklist for a map to become rankable.
As it stands, your map may face obstacles in achieving a rank due to a few identified issues (focusing on the top difficulty):
- There's some underutilized space on the playfield, noticeable if you select all objects (Ctrl + A).
- There are instances of overcrowding and messy overlaps at points like 00:10:840 (5,3), 00:14:506 (2,2), and 00:16:341 (1,2,4).
- The mapping contains instances of overemphasis on overmapped objects in certain areas, where filler 1/2 circles hold equal or more weight as circles placed to match specific sounds. For example, 00:27:840 (7,8,9) has more spacing than 00:26:673 (4,5), despite the former lacking corresponding sounds, leading to a less accurate representation of the song.
Moreover, a common mistake many new mappers make is becoming fixated on ranking a particular map, often accumulating numerous mods, as seen in examples like
beatmapsets/1785371/discussion. However, this eagerness for ranking doesn't always result in substantial improvements, leaving the maps unranked.
I've noticed your active participation in various modding queues seeking feedback for this map. My suggestion, drawing from the experiences of successful mappers, is to consider pausing work on this specific map for now. Instead, channel your efforts into mapping other songs and actively seeking feedback for those projects. Improvement often comes with practice and diverse mapping experiences.
It's common for mappers to spend 1 or 2 years refining their skills before creating maps that meet rankable standards. By broadening your mapping portfolio and continually seeking constructive feedback, you can accelerate your growth as a mapper. Once you've gained more experience and honed your skills, you'll likely find it easier to confidently rank the map you're currently working on.
